Overview

WinZip brings the convenience of Windows to the use of ZIP files without requiring PKZIP and PKUNZIP.  It features an intuitive point-and-click drag-and-drop interface for viewing, running, extracting, adding, deleting, and testing files in archives.  ARJ, LZH, and ARC files are supported via external programs.  WinZip interfaces to most virus scanners.

Windows 95 support: WinZip includes long filename support and tight integration with the Windows 95 shell.  Drag and drop to or from the Explorer, or ZIP and UNZIP without leaving the Explorer.

Internet support:  WinZip features built-in support for popular Internet file formats:  TAR, gzip, and Unix compress.  Now you can use WinZip to access almost all the files you download from the Internet.

Here's what the magazine reviews say about WinZip:

•	"These days everyone needs a good unzipping utility. This is the best.", PC Computing, 12/95

•	"Here's good news: The best zipping and unzipping program you can find is available in a Windows 95 version." Computer Shopper, 10/95

•	"WinZip 6.0 deftly integrates the best of the Windows ZIP utilities into the Windows 95 environment" PC Magazine, 9/12/95

•	"If I were stuck on a desert island with a notebook and a CompuServe account, the only utility I'd want would be WinZip", PC World 5/95

•	"WinZip compression program makes a great main squeeze", Knight-Ridder Newspapers 5/21/95

•	"Easy drag-and-drop interface when handling popular Internet file compression formats", Online Access 6/95

•	"Great for creating, exploring, and unpacking ZIP files", PC Week 4/17/95

•	"WinZip is and remains to be the most important shareware Utility for all Windows users who work with archives" CT Magazine (Germany) 5/95

Notes:

•	You can also extract files using the Drag and Drop Interface as described in the section titled Extracting Files from an Archive with the Drag and Drop Interface.

•	You can change the default Extract To directory using the Directories dialog box.


Built-in Zipping and Unzipping

WinZip will normally add files to a ZIP and extract files from a ZIP without running PKZIP and PKUNZIP.  Instead, it uses built-in zipping and unzipping.  You can switch to other windows while the built-in zipping and unzipping are running.  You can interrupt the process by pressing the Esc key or clicking in the WinZip window.  Built-in zipping and unzipping generally save time because there is no need for WinZip to start external DOS programs.  However, on some machines (particularly on slower systems) you may get faster turnaround by disabling this feature.  To disable this feature turn off the Use Internal Zipping and Use Internal Unzipping checkboxes in the Configuration dialog box.

ZIP files created by WinZip's built-in zipping are 100% PKZIP 2.0 compatible.

Built-in unzipping is not used in the following circumstances:

•	The ZIP contains files created by a version of PKZIP other than 1.1 or 2.0.

•	The ZIP spans multiple disks

•	The ZIP contains password protected files.

•	The Use Internal Unzipping and Zipping checkbox in the Configuration dialog box is not selected.

In these cases WinZip will automatically run PKUNZIP.

Built-in zipping is not used in the following circumstances:

•	One of the disk spanning options was specified in the Add or Drop dialog box.

•	A password was specified in the Password dialog box.

•	The Use Internal Unzipping and Zipping checkbox in the Configuration dialog box is not selected.

In these cases WinZip will automatically run PKZIP.

Note: you can download a pre-release 32-bit version of WinZip that does not require PKZIP for disk spanning from the WinZip home page (www.winzip.com) or the “WinZip Beta” library (lib 22) in the GO WINZIP area on CompuServe.


Viewing Files in an Archive

You can view files in an archive in several ways:

•	With the View button in the toolbar or the View entry in the Actions pull-down menu.  This activates the View Dialog Box.

•	With the features described in the section titled CheckOut Feature.

•	Most files can be viewed by double clicking on the file name in the main window's list box, as described in the section titled Double Clicking


View Dialog Box

When you push the View button in the toolbar or choose the View entry in the Actions menu the View dialog box is displayed.  This dialog gives you a choice of viewing the selected file(s) in one of three ways:

1)	Using the associated program.  The associated program is listed in parenthesis.  This method is similar to double clicking on a file in the main window unless the file is executable; in that case the file is opened with the program specified in the Default Association field in the Program Locations dialog box.

2)	Using the built-in internal ASCII text viewer.  Multiple files can be viewed in one view operation using this viewer.

3)	With any viewer available on your system.  You must specify the name of the viewer.


Built-In Viewer

The built-in ASCII text viewer can be used to view files in an archive, and is used view the results of the last operation using the View Last Output entry in the Options pull-down menu.

Unlike most dialog boxes, the viewer window can be resized and maximized.

Click on the Clipboard Copy push button to copy selected text to the system clipboard.  If no text is selected all the text is copied to the clipboard.

Notes:

•	Due to limitations in the standard Windows multi-line edit control, the built-in text viewer only displays the first 32K of a file.  However, you can view larger files by double clicking on files in the main WinZip window or by using the CheckOut facility.

•	The viewer is limited to plain ASCII text, just like the Windows Notepad application.


Select All and Deselect All

The Select All and Deselect All menu entries in the Actions menu select and deselect all files in the main window's list box.  Selected files can then be easily deleted, extracted, or viewed.


Virus Scan

Use the Virus Scan entry in the Actions pull-down menu to determine whether files in the archive contain viruses.  To use this feature a virus scanner must be configured, as described in the section titled Virus Scanner Configuration.  Note that the CheckOut feature also provides optional virus scanning.

The Virus Scan operation performs the following actions:

1)	Creates a temporary directory

2)	Extracts all files in the current ZIP to the temporary directory

3)	Runs the virus scanner against files in the temporary directory

4)	Deletes all files in the temporary directory and removes the temporary directory

5)	Displays the results of the scan operation in the View window


Creating a Self-Extracting Archive

Use the Make .EXE File entry in the Actions menu to convert the open archive to a self-extracting archive.  Self-extracting archives have an extension of .EXE, and can be run as commands.  When a self-extracting archive is run, the files in the archive are automatically extracted.  This is convenient, because the end user does not need an unzip program (like WinZip) to extract files from these self-extracting archives.

The Make .EXE File operation requires an external program.  For more information on supported external programs, including information on obtaining these programs, see the sections titled System Requirements and Installing Optional External Programs.

When working with a ZIP file, this operation runs either WinZip Self-Extractor or the ZIP2EXE program from PKWARE.  WinZip Self-Extractor creates native Windows self-extracting ZIP files, while ZIP2EXE creates DOS text mode self-extracting ZIP files.

When working with an LZH file, this operation runs the LHA program with the s option.

When working with an ARJ file, this operation runs the ARJ program with the y option.

Notes:

•	If the first file in a self-extracting LZH file is named "!" (i.e. an exclamation mark is the only character in the filename) this file will be displayed when the self-extracting executable is run.  To ensure that this file is the first file in the archive create a new LZH file, then add the "!" file (do not add other files in this step), and finally add the remaining files.

•	When using ZIP2EXE, be sure to use ZIP2EXE version 2.0 or later , otherwise you will get the message "don't know how to handle file" when running the self-extracting archive.

•	Please be sure to read the ZIP2EXE license agreement before distributing files created with ZIP2EXE.


Testing an Archive

Use the Test entry in the Actions pull-down menu to test the integrity of the open archive.  A dialog box is displayed with the results of the test operation.  This command does not require an external program when working with ZIP files.  This command runs LHA t for LZH files, and ARJ t for ARJ files.

Press the Esc key during the Test operation to terminate the integrity test.


CheckOut Feature

The CheckOut feature makes it easy to examine and/or run files in an archive.  It creates a program group containing one icon for each file in the archive.  Double click on the icon in the program group to run the file or to view the file using the program that is associated with the file (associations are described in the section titled Windows Associations).  WinZip will optionally delete the program group and related files when you close the archive or close WinZip.

Windows 95 users can access program groups from the Start menu.  Windows 3.1 and Windows NT users can access program groups from the Program Manager.

CheckOut Dialog Box

Use the CheckOut toolbar button or the CheckOut entry in the Actions pull-down menu to activate the CheckOut dialog box.  This dialog box lets you configure these aspects of the operation:

•	Use the Directory edit field to specify the temporary CheckOut directory name.  The directory will be created if it does not already exist.  The suggested directory depends on the setting of the CheckOut Base Directory in the Directories dialog box.

•	Use the Group Name edit field to specify the name to use for the program group.

•	Use the Icon Maximum for CheckOut Group edit field to specify the maximum number of icons for the CheckOut program group.  The Windows 3.1 Program Manager limits you to 50 entries, but you may prefer a lower number to save time.

•	The Run Virus Scanner check box lets you specify whether WinZip will run a virus scanner on the files in the archive.  This option is disabled unless a virus scan utility is installed in the Program Locations dialog box.

•	The Create Icons For Programs And Documents Only check box lets you control whether WinZip creates icons for all files in the archive or only for the specified files.  When this option is selected, icons are created for executable files and files with associations.  Icons are also created for any files with names starting with "read" (in order to catch files with names like "readme.1st", "read.me", etc.).

Operations performed by the CheckOut feature:

When you click on the OK button in the CheckOut dialog box, WinZip performs the following operations:

1)	If the specified directory already exists and contains files WinZip will delete the files if you give it permission.  Otherwise the directory is created.  This ensures that the directory will contain only files from the current archive.

2)	If the specified program group already exists, WinZip will delete the group if you give it permission.  This ensures that the group will contain only icons for files in the current archive.

3)	WinZip extracts files in the current archive to the specified directory.

4)	If the Run Virus Scanner check box is selected your virus scanner is run against all files in the specified directory.  If the virus scan utility returns a non-zero error level, the CheckOut operation is aborted and messages from the scanner are displayed.

5)	WinZip creates a new program group containing the appropriate icons.

Using the program group created by CheckOut:

The program group created by CheckOut works like all other program groups.  WinZip creates icons in this group for each file so that you can use them as follows:

•	If a file is executable, double clicking on the icon runs the program.

•	If a file has an association, double clicking on the icon loads the file in the associated program so you can view the file.

•	Otherwise, double clicking on the icon loads the file in the WinZip Default Association program specified in the Program Locations dialog box.


Options

Use the Configuration entry in the Options pull-down menu to activate the Configuration dialog box.  This dialog box lets you specify miscellaneous WinZip configuration information, including the default archive format and options controlling the appearance of WinZip windows.

Use the Directories entry in the Options pull-down menu to activate the Directories dialog box.  This dialog box lets you specify the initial WinZip working directory, the default Extract directory, and an optional temporary directory for use while creating archives.

Use the Font entry in the Options pull-down menu to activate the Font dialog box.  This standard dialog box lets you specify which font is used for the list of files in an archive.

Use the Password entry in the Options pull-down menu to activate the Password dialog box.  This dialog box lets you set a password for the open archive.

Use the Program Locations entry in the Options pull-down menu to activate the Program Locations dialog box.  This dialog box lets you specify the location of external programs, including PKZIP and your default file viewer.

The Sort by entries in the Options pull-down menu let you specify whether the list of files in the archive is sorted by name, path, type, size, compression ratio, compressed size, date, or whether the original archive order should be used.  Note: You can also change the sort order by clicking on the appropriate portion of the main list box header.  For example, click on the word "Date" in the header to sort by date.

The Reuse WinZip Windows entry in the Options pull-down menu determines whether a new window is opened when you start WinZip by double-clicking in the File Manager, Explorer, or Program Manager.  When this entry is checked, an existing WinZip window is used.  When this entry is not checked, a new WinZip window is created.  One advantage to reusing WinZip windows is that double clicking acts the same as drag and drop, and you never accidentally wind up with multiple WinZip windows.

The Save Settings on Exit entry in the Options pull-down menu determines whether options are automatically saved when WinZip is closed.

The Save Settings Now entry in the Options pull-down menu saves the options immediately.  Options that are saved and restored include all the options in the Options pull-down menu, all options in the Add, Configuration, and Extract dialog boxes, and the current screen size and location.  The options in the Directories Dialog Box and the Program Locations Dialog Box are saved regardless of whether Save Settings on Exit is checked.

The Set Installation Defaults entry in the Options pull-down menu sets all configuration options and directory names to the original installation defaults.

Use the View Last Output entry in the Options pull-down menu to display the results of the last command issued by WinZip.


Configuration Dialog Box

Select Configuration from the Options menu to activate the Configuration dialog box.  This dialog box lets you specify

•	Whether the normal prompt dialog boxes are displayed in the following circumstances:

1.	When a file is dropped on WinZip.  If no prompt is displayed, the file is automatically added to the open archive using the options last specified in the Drop dialog box.  Note that when an archive is dropped on WinZip the archive is opened regardless of this setting.

2.	When a file is dragged from WinZip to another application.  If no prompt is displayed, the file is automatically extracted using the options last specified in the Extract dialog box.

3.	When the View button is pushed.  The selected file(s) are automatically viewed.  Note that when View is selected from the Actions pull-down menu this setting is ignored.

4.	When the Extract button is pushed.  The selected file(s) are automatically extracted using the options last specified in the Extract dialog box.  Note that when Extract is selected from the Actions pull-down menu this setting is ignored.

Note: you can toggle these settings by holding down the shift key.  For example, if the Prompt When Extract Button Is Pushed option is checked, you can bypass the Extract dialog box by holding down the shift key while pressing the Extract button.

•	The Default Archive Format.  This format is used when you specify the name of an archive without an extension while creating or opening an archive, and when creating an archive with an extension other than .ZIP, .LZH, or .ARJ.

•	Whether WinZip should automatically show the Open Archive dialog box when you start WinZip.

•	Whether WinZip should try to use Built-in Zipping and Unzipping when possible, instead of running PKUNZIP.

•	Whether WinZip should beep after archive operations that take more than one second to complete.

•	Whether the background on the header is displayed in light or dark gray.

•	Whether "Smart DOC Handling" is enabled.  This feature is described in the section titled Double Clicking.

•	Whether the right mouse button displays a pop-up menu or is used to select files in the main WinZip window.

•	Whether WinZip should enable/disable PKZIP 2.0's use of DPMI, EMS, and XMS, and whether the PKZIP "slow memcopy" switch should be used.  PKWARE recommends that DPMI and XMS be disabled under Windows.  See your PKWARE documentation for details on these settings.

•	Whether WinZip should maintain a log of all error messages and all external commands it issues. Examples of external commands are PKZIP, LHA, and ARJ.  You can specify the drive used for the log file.  The log is written to the file WINZIP.LOG in the root directory of the selected drive.

•	Whether WinZip should list the files in the archive in lowercase for improved legibility.

•	Whether WinZip should have the "always on top" attribute, so that it is not overlaid by normal windows.

•	Whether "smart" CR/LF conversion should be performed when extracting from TAR files.  CR/LF is short for Carriage Return/Line Feed, the standard end of line indicator.  This option can be useful when a TAR file contains text files created on a Unix or Macintosh machine.  Unix text files usually contain lines ending in Line Feed characters only, and Macintosh text files usually contain lines ending in a Carriage Return character.  The standard Windows Notepad program and many other Windows programs require a Carriage Return and Line Feed at the end of each line.  When the TAR File Smart CR/LF Conversion option is in effect, WinZip determines whether to perform CR/LF conversion for each file inside a TAR file by looking at the first 80 characters in each file.  If the file is a text file then single LF and CR characters are converted to CR/LF pairs so the file can be viewed by Notepad and other Windows viewers.  Files are considered text when the first 80 bytes contain only characters with ASCII values between 0x20 and 0x7f, carriage returns, line feeds, form feeds, tabs, and other alphanumeric characters (as determined by the Windows IsCharAlphaNumeric API).

•	Whether WinZip displays large push buttons.  The default for this setting depends on your video setup.

•	Whether compressed file sizes and the compression ratio should be displayed in the main WinZip listbox.

•	Whether icons are shown next to each entry in the main listbox to indicate whether a file is executable or has an association.

•	Whether WinZip should display 3D dialog borders instead of the normal dialog borders (this option is not available under Windows 95).


Directories

Select Directories from the Options menu to display the Directories dialog box.  This dialog box lets you specify the following information:

Start-up Directory

Unless you start WinZip by double clicking on an archive, WinZip will optionally change to a directory of your choice when it starts up.  Files in this directory are automatically displayed in the Open Archive and New Archive dialog boxes.  The following choices control which directory is used.

•	System default - WinZip does not change directories, so the system default directory is in effect.  Usually this is the directory containing WINZIP.EXE or WINZIP32.EXE.

•	Last Open Archive - WinZip changes to the directory containing the last open archive during your last WinZip session.

•	Directory: - WinZip always changes to the specified directory.

Default Extract Directory

These selections determine the default directory that WinZip automatically lists in the Extract To field in the Extract dialog box.  You can, of course, type over this default directory name or select a different directory from the directory listbox.

•	Open Archive Directory - WinZip lists the name of the directory containing the open archive in the Extract To field.  For example, if the archive c:\download\tools.zip is open, WinZip will list c:\download.

•	Last Extract Directory - WinZip will list the name of the directory you used during the last Extract operation.  This value is saved when you exit WinZip so you can use it during your next WinZip session.

•	Directory - WinZip always lists the specified directory.  This value is saved when you exit WinZip so you can use it during your next WinZip session.

Default Add Directory

These selections determine the default directory when the Add dialog is opened.

•	Open Archive Directory - WinZip uses the directory containing the open archive.

•	Last Add Directory - WinZip uses the directory you used during the last Add operation.  This value is saved when you exit WinZip so you can use it during your next WinZip session.

•	Directory - WinZip always uses the specified directory.  This value is saved when you exit WinZip so you can use it during your next WinZip session.

Optional Working Directory

If specified, temporary ZIP files are created in this directory.  If this option is not specified, temporary ZIP files are created in the directory containing the open ZIP file.  This option is particularly useful when you are updating an archive and there is not enough room on the destination drive for both the original archive and the updated archive.  This is most likely to occur when you are working with removable media (e.g. floppy disks).  You can tell WinZip to use this feature only when working with ZIP files on removable media by checking the Use for Removable Media Only checkbox.

When using PKZIP to create an archive WinZip specifies this directory name via the -b switch.  When using ARJ to create an archive WinZip specifies this directory name via the -w switch.

CheckOut Base Directory

If specified, WinZip uses this directory as the prefix for the default directory in the CheckOut dialog box.  If this field is left blank WinZip will instead use the directory containing the open archive.

Temp Directory

This entry specifies the location for temporary files created by WinZip, including files created during the View and Virus Scan operations.    If you run out of disk space during a View or Scan operation, change the Temp Directory to specify a drive and directory with sufficient free space.


Password Protection

Files in ZIP and ARJ archives can be password protected by specifying a password in the Password dialog box.  To access this dialog box use the Password entry on the Options pull-down menu.

If a password is specified then the password will be used to encrypt and decrypt files subsequently added to the archive or extracted from the archive.  This feature can be useful to protect data when storing archives with sensitive information in unsecured places.

If a password is active the Add dialog box title will indicate that files will be password protected.  The main WinZip window lists password protected files with a plus sign following the filename.

To use password protection:

1.	Open or create an archive.  If you are using the New dialog box uncheck the Add Dialog checkbox at the right of the dialog box.

2.	Select Password from the Options pull-down menu, specify a password, and press OK.

3.	Perform any action, e.g., View, Extract, Add, or Drag and Drop.

Notes:

Passwords are cleared (reset so that no password is in effect) when an archive is closed or another archive is opened.

If a ZIP file contains password protected files, PKUNZIP is always used to extract files.

Be sure to remember any passwords you use!  If you forget a password then the files protected by that password cannot be recovered!


Program Locations

Select Program Locations from the Options menu to activate the Program Locations dialog box.  This dialog box lets you specify the paths and filenames for the optional external programs supported by WinZip.  Note that these programs are not required for most operations involving ZIP files.

If you are installing WinZip and are not familiar with these programs you can just press the OK button to continue the installation procedure.

External programs are not distributed with WinZip.  For more information on these programs, including availability and minimum version numbers, see the section titled System Requirements.  For step by step installation examples for external programs see the section titled Installing Optional External Programs.

When WinZip is installed it will attempt to locate the default programs in the directories specified in your PATH= environment variable.  If it cannot find these programs, it will leave the corresponding edit fields blank.

If a program is not installed on your system, just leave the corresponding edit field blank.  Otherwise, fill in the program name.  The extension defaults to EXE.  If no path is included for an entry, WinZip assumes that the program is in a directory specified in your PATH= environment variable.

See the section titled Virus Scanner Configuration for information about that portion of the Configuration dialog box.

Example:

The first entry in the dialog box, which is for PKZIP, can have one of three values:

Value	Description
	If the entry is blank, WinZip assumes that PKZIP is not installed on your system.
PKZIP.EXE	Just the filename is needed if PKZIP.EXE is in a directory specified in your PATH= environment variable.
C:\PKWARE\PKZIP.EXE	The full drive, directory, and filename are required if PKZIP.EXE is not in a directory specified in your PATH= environment variable.  Note that C:\PKWARE is just an example, any other directory can be used.
Make EXE File:

You can use either WinZip Self-Extractor or ZIP2EXE for this entry.

Default Association

The program specified as the Default Association is used when viewing a file that does not have an association.  For additional information on associations, see the section titled Windows Associations.

The defaults for this field are:

•	SCCVAPI.EXE, System Compatibility Corporation's "Outside In" file viewer, if it is found in a directory specified by your PATH= environment variable.

•	NVIEWER.EXE, the Norton Desktop for Windows File Viewer, if it is found in a directory specified by your PATH= environment variable.

•	WNFV.EXE, the PC Tools for Windows File Viewer, if it is found in a directory specified by your PATH= environment variable.

•	NOTEPAD.EXE, the Windows Notepad program, if NVIEWER and WNFV are not found.

Almost any other file viewer or editor can be used.


Virus Scanner Configuration

WinZip supports many virus scanners that can be run from Windows or from the DOS command line, with a few important limitations noted below.  Virus scanners can be run using the Scan entry in the Actions menu or during CheckOut operations if the Run Virus Scanner option in the CheckOut dialog box is selected.

Virus scanner configuration is done from the Program Locations dialog box.  Select Program Locations from the Options menu to activate this dialog box.   WinZip will automatically search for the following virus scanners in the directories specified by your PATH= environment variable.

Scanner	Parameters

SCAN95.EXE	*.* /autoscan /nosplash

NAVW32.EXE	*.* /s

NAVW.EXE	/auto *.* /S

WNAPVIR.EXE	/QM/M-/B- *.*

NAV.EXE	*.* /m- /s

CPAV.EXE	*.* /P

MSAV.EXE	*.* /P

WSCAN	%wscan

SCAN.EXE	/nomem *.* /ALL /SUB

WFINDVIR	%d

TBSCAN	*.* %d ln=%f lo nb nm

F-PROT	/NOBOOT /NOMEM /LIST *.* /REPORT=%f

You can also configure WinZip to work with another scanner.  See the section titled Virus Scanner Configuration Details below for more information.

If any of the aforementioned programs are in a directory specified by your PATH= environment variable when WinZip is first installed, WinZip will automatically fill in the Program Locations dialog box with the appropriate options from the table above.  There is no need to modify these parameters.

If the scanner is not in a directory specified by your PATH= environment variable, you can have WinZip automatically fill in the Parameters field by selecting the desired scanner from the drop-down combo box (for example, scan.exe) and then adding the full filename for the scanner to the Scanner field (for example, c:\mcafee\scan.exe instead of just scan.exe).

Notes:

The default parameters in the table above work with the versions of the scanners that were tested.  If the authors of a scanner change the command line parameters in future releases of the scanner, then WinZip's default parameters for the scanner may no longer work.  For example, McAfee SCAN 2.1 parameters are incompatible with prior versions of SCAN.  Version 2 requires the /ALL parameter while version 1 requires /A.

Unless a virus is found, no manual intervention is required while running most virus scanners.  However, the WSCAN and TFINDVIR scanners always need to be closed manually, because they do not currently support options to close automatically.

Virus Scanner Configuration Details

This portion of the documentation describes how to configure WinZip to work with a scanner that is not listed above.  Do not use WinZip's virus scanning support with a different virus scanner unless you have read and understood the following information.

To configure WinZip to work with a scanner, fill in the following fields in the Program Locations dialog box:

1)	The Scan Program field should contain the name of the program (the full path name is required if the program is not in a directory specified in your PATH= environment variable).

2)	The Parameters field should contain the appropriate parameters to run the virus scanner as described below.

3)	The Run Minimized box determines whether the scanner should be run as an icon.  See below for important notes on using this parameter with DOS based scanners.  Note that the NAVW32.EXE scanner always runs minimized, regardless how you set this option.

Special character sequences for the Parameters field are:

*.*	indicates where WinZip should substitute the drive, directory, and the *.* characters for the files that are to be scanned.  For example, "c:\temp\dir\*.*".
%d	indicates where WinZip should substitute the drive and directory of the files that are to be scanned.  Note that the wild card characters *.* are NOT included when you use %d.
%f	indicates where WinZip should substitute the name of a temporary "report file".  Report files should ONLY be used when running DOS virus scanners.
%wscan	a special parameter required for McAfee's WSCAN program.
If you do not specify any of the aforementioned special character sequences WinZip will append the filenames to be scanned at the end of the scanner command line.

Be sure to specify any parameters necessary to cause the scanner to check subdirectories of the drive and directory of the files that are to be scanned.

To configure WinZip for a Windows based virus scanner, first ascertain that the virus scanner reports suspected viruses by displaying a dialog box.  If the scanner simply writes to a log file when a virus is found you (and WinZip) will not know about the problem.

To configure WinZip for a  DOS based virus scanner, be sure to verify that the scanner can either be used with the Run Minimized option (see below for details) or issues a prompt if a virus is found.  If neither of these conditions is met and a virus is found you (and WinZip) will not know about the problem.

The Run Minimized check box should only be used for DOS scanners under the following circumstances:

1)	The scanner is configured to run in "batch" mode, without any prompts.  If the scanner requires any keyboard input when running as an icon, you will not be able to see the prompts, and the session will appear to be hung.

2)	The scanner writes all messages through DOS, or has an option to write results to a report file.  Messages written directly to the video buffer are not captured by WinZip and will be lost.  To determine whether a scanner writes messages through DOS, run the scanner with its output redirected (for example, issue the command "scan > nul").  Any messages you see during this test will not be captured by WinZip.  If the scanner has an option to write results to a report file you can use %f in the Parameters field to cause WinZip to capture the results (see above for details).

3)	The scanner returns a non-zero error level if it encounters any problems.  If the scanner does not return a non-zero error level, WinZip will assume that the files passed the virus check, and any warnings issued by the scanner will be lost.  (Note: if the scanner returns a non-zero error level, WinZip automatically displays all messages written to standard error or standard output.)


Create Directory

This dialog box lets you create a directory.  This directory becomes a subdirectory of the current directory unless you specify a path.


Double Clicking

Double clicking on a filename listed in the main WinZip window will perform the same action performed when you double click on a file in the File Manager or Explorer.  If the file is executable (has a filename extension of EXE, COM, BAT, or PIF) WinZip will run it.  Otherwise WinZip will open the file with the appropriate application.  For example, files with a filename extension of .WRI are opened by the Windows Write application.  The appropriate application is determined via Windows Associations.  If no application is associated with the file, WinZip will run the program specified as the Default Association in the Program Locations dialog box.  If you modify the file while viewing it, WinZip will offer to add the modified file to the archive.

If the Smart DOC Handling option in the Configuration dialog box is enabled and you double click on a file with a file type of .DOC, WinZip will run one of two programs:

1)	If the .DOC file looks like plain ASCII text WinZip will run the program specified as the Default Association in the Program Locations dialog box.

2)	If the .DOC file looks like a file created by a word processor WinZip will run the program associated with .DOC files.

Smart Doc Handling avoids the overhead of loading a word processor like Word for Windows when viewing ASCII text files like "readme.doc".

Note: Pressing the Enter key performs the same action as double clicking.


Windows Associations

Microsoft has defined the word "associate" as follows:

To identify a filename extension as belonging to a certain application, so that when you open any file with that extension, the correct application is opened automatically.

For example, by default, Windows associates .WRI files with the WRITE application, and .CRD files with the CARDFILE application.  Most Windows application installation procedures create associations.  For example, Word for Windows creates an association for .DOC files, while WinZip creates associations for files with the extensions ZIP, LZH, ARJ, ARC, TAR, TGZ, TAZ, GZ, and Z.

WinZip uses associations when you Double Click on a filename listed in the main WinZip window and when you use the CheckOut Feature.

WinZip, the Explorer, the Program Manager, and the File Manager all use associations the same way.  When you double click on a file with an association, the application associated with the file is run, and the application automatically opens the file.  The WinZip CheckOut facility establishes associations when it updates the CheckOut program group for two reasons: to display the right icon for each file, and to ensure that the appropriate application is run when you double click on an icon.

Under Windows 95 you can view, add, and remove associations using the File Types tab in the Options dialog box in My Computer or the Explorer.  Select Options from the View pull-down menu in My Computer or the Explorer, then click the File Types tab.  Press the F1 key for detailed instructions.

Under Windows 3.1 and Windows NT you can view or add associations using the Associate entry in the File Manager's File pull-down menu as follows: start the File Manager and select a filename with the extension you are interested in.  Then choose the Associate entry in the File Manager's File pull-down menu.  Press the F1 key for details.


Using Extended Selection List Boxes

WinZip uses Extended Selection List Boxes for the list of files in the open archive and for the list of files in the Add dialog box.  You can select files from an Extended Selection List Box in the same way that you select files in the File Manager or Explorer.

To select an individual file in an Extended Selection List Box, click on the file.  This cancels all previous selections.  To select two or more files in sequence, click on the first file, then press and hold down the Shift key while you click on the last file in the group.  To select two or more items out of sequence, press and hold down the Ctrl key while you click on each file.

In addition to the aforementioned standard methods for working with Extended Selection List Boxes, you can use the right mouse button to select files without canceling previous selections.  This feature was added for compatibility with Norton Desktop for Windows.

You can use the Select All and Deselect All entries in the Actions pull-down menu to select and deselect all files in an archive.

The keyboard interface for Extended Selection List Boxes is described in the section titled  Keyboard Usage.


Multiple Disk Spanning

The "Multiple Disk Spanning" feature allows you to create and access archives that span multiple floppy disks.  This feature is useful when the data being archived does not fit on one floppy disk.  It is available via the Add and the Drop dialog boxes.

Requirements for multiple disk spanning:

1)	You MUST create (or open) an archive on a floppy drive before using this feature, otherwise multiple disk spanning options are disabled.

2)	If you are working with a ZIP file you MUST have PKZIP installed in the Program Locations dialog box.  PKZIP 2.04g or later is REQUIRED for multiple disk spanning of ZIP files.  See the section titled System Requirements for details on this requirement.

Note the following restrictions:

•	ZIP files: Any files in the open archive will be replaced (a confirmation dialog is displayed before data is replaced).  If any of the "destructive" spanning options (e.g. "format" or "wipe disk") are specified, all data currently on the disk will be lost.  For details on the options, see the "Backup Guide" in your PKZIP version 2.04 documentation.

•	ARJ files: WinZip automatically provides non-destructive disk spanning for ARJ files on removable media by using the -vva option for add, move, freshen, and update operations.

•	LZH files: The LZH format does not support disk spanning.

Problem Solving:

If the Multiple Disk Spanning options in the Add and Drop dialog boxes are disabled even though the above requirements are met, check the date/time stamp on your PKZIP.EXE.  You can check the date/time stamp as follows:

1.	Activate the File Manager.

2.	Navigate to the directory containing PKZIP.EXE.

3.	Select All File Details from the File Manager's View pull-down menu.

WinZip uses the date/time stamp on your PKZIP.EXE to determine whether you have the correct version of PKZIP installed.  All official versions of PKZIP 2.04g are dated 28-Dec-92 or later.  If your PKZIP.EXE is dated prior to 28-Dec-92 you should reinstall PKZIP to solve this problem.

***

Note: you can download a pre-release 32-bit version of WinZip that does not require PKZIP for disk spanning from the WinZip home page (www.winzip.com) or the “WinZip Beta” library (lib 22) in the GO WINZIP area on CompuServe.


Enhanced and Standard Modes

Windows 3.1 Only  In Windows 386 Enhanced mode PKZIP, PKUNZIP, LHA, and other optional programs run by WinZip are executed in the background in an iconized DOS session.  While these commands are running you can switch to another window using the Task Manager or by clicking on the desired window.  An hourglass pointer is used to indicate that the WinZip window is busy.  You can double click on the icon titled "WinZip running DOS commands" to monitor the command's progress.  If any of these commands prompts the user for input, WinZip will automatically bring the DOS session to the foreground.

Unfortunately, Windows does not allow you to execute these commands in the background under Standard mode.  In Standard mode your screen will be cleared, and these commands will be run in a full screen DOS session.

In all cases you can view the messages displayed by the last command issued by WinZip by selecting View Last Output in the Options pull-down menu.

Your Windows User's Guide contains descriptions of Enhanced and Standard modes.  You can determine which mode is active by choosing the About entry in the Program Manager's Help pull-down menu.


Norton Desktop For Windows

Windows 3.1 Only

NDW 3.0 Notes:

•	You can open archives with WinZip by double clicking in the NDW Drive Window if you turn off the Show Zips As Directories entry in the Drive Window's Tree menu.  Be sure to save your NDW settings after making this change.

•	If you installed NAVW (Norton Anti-Virus for Windows) as your WinZip virus scanner while running NDW 2.0, you will have to change the Virus Scanner Parameters in WinZip's Program Locations dialog box.  Simply remove the /auto portion of the parameters.  This switch is still required for earlier versions of NAVW.

•	The initial release of the German version of NDW 3.0 has a bug that prevents the CheckOut and Install options from creating program groups.  Symantec is working on a fix.

•	The features described in the section titled File Manager Interface all work with Norton Desktop drive windows.  Note: if you have added the MaxWinFileExtensions=0 line to your NDW.INI, the WinZip menu will not be displayed in NDW drive windows.  In this case you'll have to increase the value of this configuration option to see the WinZip menu.

NDW 2.0 Notes:

•	Several Norton Desktop 2.x users have reported that the WinZip CheckOut feature sometimes places icons into the wrong group.  This is apparently caused by a bug in NDW 2.x.  This problem is easy to fix:  select Quick Access from the NDW Window pull-down menu to display all groups.  Delete any duplicate groups, or groups that should not be listed (e.g. groups for products that have been uninstalled).  Then select Save Configuration from the NDW Configuration pull-down menu.  At this point the problem should not re-occur.


Norton Navigator for Windows 95

Windows 95 Only

Restoring the association for ZIP files after installing Norton Navigator:

Norton Navigator SETUP associates ZIP files with Norton Navigator.  If you subsequently run WinZip it will offer to re-associate itself with ZIP files.  If you choose "Yes" you can use WinZip exactly as you did before installing Norton Navigator.  Note:  it is possible the icons for ZIP files will not change until you re-boot Windows 95.

Using WinZip with Norton File Manager:

You can start WinZip by double clicking on ZIP files in Norton File Manager after following these steps:  (1) select General from the Norton File Manager Options menu, (2) in the Advanced tab uncheck the "Show compression files as folders" checkbox, and (3) press OK.

Restrictions:

The Norton File Manager does not support Explorer shell extensions, so you cannot use the WinZip shell extension to drag a ZIP to a folder to unzip it.  However, you can still do this after installing Norton Navigator by running the Windows 95 Explorer or by double clicking on My Computer.


Keyboard Usage

WinZip is easier to use with a mouse, but you can also use the standard Windows keyboard interface.  Keyboard accelerators defined for WinZip include:

Ctrl+N	Create a new archive.
Ctrl+O	Open an existing archive.
Ctrl+L	Close an archive.
Ctrl+F	Display Information about the open archive.
F7	Move an archive
F8	Copy an archive
Ctrl+R	Rename an archive.
Ctrl+M	Mail an archive.
Ctrl+A	Add files to an archive.
Ctrl+D	Delete files from an archive.
Ctrl+E	Extract files from an archive.
Ctrl+V	View files in an archive.
Ctrl+Slash (/)	Select all items in the list box.
Ctrl+Backslash (\)	Cancel the selection of all items in the list box.
Ctrl+S	Run virus scanner.
Ctrl+T	Test an archive.
Ctrl+K	Create a self-extracting archive.
Ctrl+C	Activate the CheckOut feature.
Ctrl+I	Install files in an archive.
Direction key(s)	Move the cursor or scroll to other items in a list box.
Shift+direction keys	Select multiple items in a list box.
Enter	Same as Double Clicking in the main window listbox.
Shift+F8	Toggle "add mode" on and off.  When add mode is on, the selection cursor blinks.  In this mode you can use the Spacebar to select non-consecutive items in the list box or to cancel the selections.  Press Shift+F8 again to end add mode.  Clicking the left mouse button cancels any selections.


Ideas for Future Enhancements

Ideas for future enhancements include:

•	Support for other archive file formats, including RAR, PAK and ZOO.

•	Built-in ARJ and LZH file extraction.

•	Support for all ZIP, LZH, and ARJ options, including comments, volume labels, and authenticity verification (AV number support).

•	Additional support for printing (Windows 95 users can drag files to a printer icon or shortcut).

•	Uuencode/decode support.

•	User configurable toolbar.

Additional suggestions from all users are welcome.


Hints and Tips

Here are some hints and tips you may find useful:

•	Learn to use the Windows help system!  All Windows programs use the same help system, so you will quickly make up for the time you spend learning it by being more productive in all your Windows applications.  To get started select How to Use Help from the Help menu.

•	Read the section Brief Tutorial if you have not yet done so.

•	Windows 95 users: see the section titled Windows 95 Quick Examples for many useful hints.

•	Windows 3.1 and Windows NT users: use the File Manager instead of the Open dialog box to select archives you want to open.  Unlike the standard Windows Open dialog box, the File Manager lets you sort archives by date and size.  To open an archive from the File Manager either double click on the archive or use the Drag and Drop Interface to drop an archive from the File Manager onto WinZip.

•	Use the Drag and Drop Interface to add files to archives.  The main advantage to using the Drag and Drop interface over using the Add Dialog Box is that you can sort files by date and size in the File Manager, making it easier to find the files you want to add.

•	If you usually use the same directories when opening, extracting, or adding files, specify those directories in the Directories dialog box.  Choose Save Settings Now from the Options pull-down menu to save your changes.

•	To change the default WinZip window size and position to the current window size and position, choose Save Settings Now from the Options pull-down menu.

•	To switch to another program during an archive operation, click on the window for the other program, or bring up the Task Manager by double clicking over the desktop or pressing Ctrl+Esc.  Note: you cannot use the WinZip system menu or minimize button while WinZip is executing a DOS command.

•	To interrupt an archive operation click on the WinZip window.  This will activate the Operation Interrupted dialog box.

•	Click on the Status bar to display the Archive Information dialog box.

•	Click on the header in the main window to sort the list of files.  For example, click on the word "name" in the header to sort the list by name.

•	WinZip determines what drive and directory to use for temporary disk files by checking the value of the WZTMP=, TMP=, TEMP=, and PKTMP= environment variables, respectively. If none of these environment variables is set, WinZip uses the root directory of your C: drive.  You can override this default by specifying a value as the Temp Directory in the Directories dialog box.  Choose Save Settings Now from the Options pull-down menu to save any changes.

•	There are two ways to bypass the dialog boxes displayed when you drag files, drop files, and press the Extract or View button:  (1) hold down the shift key while performing the operation, or (2) if you usually want to bypass the dialog box, turn off the appropriate option as described in the section titled Configuration Dialog Box.

•	You can open archives with WinZip by double clicking in the Central Point Desktop 2.0 File Manager if you turn off the Show Compression Files entry in the CPS File Manager's Tree menu.

More Hints and Tips

•	Under Windows 3.1 You can change the default WinZip icon as follows:

1.	Click on the WinZip icon.

2.	Press Alt+Enter, or press Alt while double clicking on the icon.  The Program Item Properties dialog box appears.

3.	Click on Change Icon.

4.	Double click on your preferred icon.

5.	Choose OK.

•	You can use the right mouse button to select files in the main WinZip listbox without canceling previous selections.  This is often easier than using the standard shift-click method.  For more information on selecting multiple discontiguous files in the main WinZip list box, see the section titled Using Extended Selection List Boxes.

•	If you have a large RAM disk, use it as a temp directory to significantly speed up many archive operations.

•	You can move or copy files from one archive to another by opening multiple WinZip windows, one for each archive, and dragging files from one to the other.  Note that you need to turn off the Reuse WinZip Windows entry in the Options pull-down menu in order to start multiple WinZip windows.

•	Under Windows 3.1 and Windows NT you can start WinZip every time you start Windows by adding the WinZip icon to the "Startup" program group.  Be sure to select the Run Minimized checkbox in the Properties dialog box.

•	WinZip can now be used to compress files with cc:Mail.  To use this feature change the compress= line in the [cc:Mail] section of the appropriate WMAIL.INI files to specify the full path for WinZip followed by "-a %1 @%2".  For example, if WinZip is installed in your c:\winzip directory, specify

compress=c:\winzip\winzip.exe -a %1 @%2


Version History

WinZip 6.0a features improved Windows 95 drag and drop support.  WinZip 6.0 added many Windows 95 features, including tight integration with the Windows 95 shell and Explorer-style dialog boxes.  Other enhancements included an improved interface to file viewers, an "Express Setup" option, and better support for virus scanners.  WinZip 5.6 added support for the popular Internet file formats TAR, gzip, and Unix compress.  WinZip 5.5 (16-bit version only) added the ability to install, try, and UNINSTALL software distributed in ZIP files.  This feature runs the install program in a ZIP, gives you a chance to try the program, and optionally deletes any new files, icons, program groups, and restores any altered INI files.

Changes in WinZip 6.0a

WinZip 6.0a features improved Windows 95 drag and drop support.  You can now extract files from the main WinZip window using drag and drop to the Explorer or to the Windows 95 Desktop.  You can also drag files to an application shortcut to open the file using the application, or drag files to a printer to print.

Here is a summary of Windows 95 Drag and Drop facilities.
Features marked with an asterisk are new in WinZip 6.0a.

  Drag from  Drop on       Result
  ---------  -------       ------
 *WinZip     Explorer      selected files are extracted
 *WinZip     App Shortcut  selected files are opened with shortcut
 *WinZip     Desktop       extract to desktop for easy access
 *WinZip     Printer       file is printed
  WinZip     Open App      file is opened in the application
  Explorer   WinZip        drop files to add them to an archive
  Explorer   WinZip        drop an archive to open it
  Explorer   Explorer      drop files on a ZIP to add them
  Explorer   Explorer      right button drag a ZIP to a directory
                             to extract

Aside from the Windows 95 drag and drop improvements, WinZip 6.0a is a maintenance release, with support for programs that became available after WinZip 6.0 shipped (Norton AntiVirus and Scan 95) and a few bug fixes.  For a list of changes see the section titled WinZip 6.0a Maintenance Release Details.


WinZip 6.0a Maintenance Release Details

•	Norton AntiVirus 95 (NAVW32) and McAfee Scan95 are now in the list of supported virus scanners.  WinZip searches for SCAN95 and NAVW32 in the registry, not just the PATH= environment variable, so they are more likely to be found if they are installed.

•	WinZip can now launch Norton Antivirus (NAVW32.EXE) even if the Norton directories are not specified in your PATH= environment variable.

•	Checkout with "Icon Maximum" set to zero now gives you the opportunity to delete the checked out files when the archive is closed.

•	Self-extracting ZIP used for installation of the shareware evaluation version automatically cleans up temporary files.

•	Setup for the 32-bit version now will not run on Windows 3.1+Win32S

•	Under Windows 95 archives are only added to the Start->Documents menu if they are associated with WinZip.

•	PgDn key now works under Windows NT (NT ignores the PgDn key in listboxes with the LBS_OWNERDRAWVARIABLE and LBS_HASSTRINGS styles).

•	If the PKZIP "Insert disk #2 - Press a key when ready" message is issued more than once a dialog box with help for the problem is displayed when the PKZIP command terminates.

•	Install feature now recognizes Win32 SETUP programs.

•	Register button added to the About box in unregistered version.

•	Under Windows 95, drag and drop from WinZip to an open application now has the same effect as double clicking; the Extract dialog box is not displayed.

•	Shorten any long path names of external programs run via DOS.

•	Alt-E no longer a duplicate shortcut in the Extract dialog box.

•	Missing ellipsis in Explorer Configuration menu entry added.

•	"Add to Zip" Add dialog box now never appears BEHIND WinZip.

•	Proper message issued when trying to use internal viewer on files larger than 32k under Windows 95.

•	View dialog box "View with Association" option now works on files with no association.

•	Fixed rare gp fault in Program Locations dialog box.

•	WinZip now uses long filenames when files are dropped on a WinZip shortcut or via the Send To menu.

•	If you prefer to have the Open and New dialog boxes start out in "Details" view, use a text editor to add the line OpenDetail=1 to the [WinZip] section of the winzip32.ini file in your Windows 95 directory.  This feature uses an undocumented aspect of the common dialog boxes so it may not work in future versions of Windows.

For a description of the drag and drop improvements see the section titled Changes in WinZip 6.0a.


Changes in WinZip 6.0

The most significant changes in WinZip 6.0 is the new Windows 95 support, detailed in the section titled WinZip for Windows 95.

Other changes include:

•	WinZip now allows you to view multiple files in an archive without first closing the first file (earlier versions of WinZip restricted you to closing the first file before viewing the second file).  Under Windows 95 the system "Quick View" program is normally used as the "Default Association" used to view to files not associated with another program.  Here are some implementation details:  when you double click on a file in an archive, WinZip extracts the file to the "Temp Directory" specified in the Options/Directories dialog box.  WinZip then runs the program associated with the file so you can view the file.  When you later close the archive WinZip deletes the temporary file(s).  If the file(s) have been modified WinZip will give you an opportunity to update the archive with the modified file.  The "Always on Top" flag is temporarily turned off if it is on when you view a file, and is turned back on the next time you activate WinZip.

•	The File Manager Extension is now implemented under Windows 95, and Windows NT.  You will have to choose File Manager Configuration from the Options menu and check the second button to activate this feature.  The File Manager Extension works the same as it does under Windows 3.1.

•	The WinZip installation procedure now includes "Express Setup" and "Custom Setup" options.  Custom Setup results in the "old" WinZip 5.6 behavior.  Express Setup, the default, skips the Program Locations dialog box, the File Manager Configuration dialog box, and "Create Program Group" prompt.

•	With more and more people using the Internet, virus scanning is more important.  As a result, WinZip's support for virus scanners has been improved.  The virus scanner parameters field now supports two new special values:  %d represents the directory containing the files to be scanned (without a trailing *.*), and %f represents a temporary "report" file.  %wscan is a special parameter that should be used only for McAfee's WSCAN 2.14 and compatible scanners.  WinZip now searches for and supplies default parameters for four additional scanners:  wscan, f-prot, tbscan, and wfindvir.  The "Run as Iconized DOS Session If Possible" checkbox has been replaced with the "Run Minimized" checkbox, which is now used for both DOS and Windows scanners.

•	The number one new support problem in WinZip 5.6 was caused by the "TAR File LF to CR/LF Conversion".  This option, intended for text files only, caused problems for binary files.  The option has been replaced by the "TAR File Smart CR/LF Conversion" option.  When this option is in effect WinZip determines whether to perform CR/LF conversion for each file by looking at the first 80 characters in the file.  If the file is a text file then single LF and CR characters are converted to CR/LF pairs so the file can be viewed by Notepad and other Windows viewers.  Files are considered text files when first 80 bytes contain only characters with ASCII values between 0x20 and 0x7f, carriage returns, line feeds, form feeds, tabs, and other alphanumeric characters (as determined by the Windows IsCharAlphaNumeric API).


Changes in WinZip 5.6

Internet File Format Support In WinZip 5.6

The Internet is becoming more and more popular, and unlike CompuServe and most other online services, not all parts of the Internet have standardized on the ZIP file format.  Many Internet sites distribute files in "gzip" and Unix "compress" format (files ending in GZ or Z) and use the old TAR (Tape ARchive) format to group files.

WinZip 5.6 adds support for the TAR, gzip, and Unix compress formats.  This means you can use WinZip to work with almost all compressed files downloaded from the Internet.  WinZip 5.6 also lets you decompress files in the "Microsoft Compress" format (LZEXPAND) used on the Windows 3.x distribution disks and some other Microsoft product distribution disks.  No external programs are needed for these file formats.

Some notes on the new Internet file format support:

•	WinZip does not let you create files in these formats, but other features (Extract, View, CheckOut) all work.

•	Unlike ZIP, TAR, LZH, ARJ, and ARC files, Microsoft-compressed files and Z files (gzip/compress) contain only ONE file.

•	Unlike ZIP, LZH, ARJ, and ARC files, TAR files are NEVER compressed.

•	Since TAR files are often distributed in Z format (with extensions like .TAZ and .TGZ) WinZip treats Z files containing a TAR file as a special case:  WinZip offers to decompress and open the TAR file.

•	There is no reliable way to determine the uncompressed size of files in the gzip and compress format, so WinZip shows the size as a question mark.

Other Changes in WinZip 5.6:

•	A new checkbox in the Configuration dialog box determines whether the right mouse button activates a pop-up menu or selects listbox entries as in earlier versions.

•	Conversion from long file names to MS-DOS 8.3 filenames is smarter than in previous versions:  a name like XXX.YYY.TXT is now converted to XXXYYY.TXT rather than being truncated to XXX.YYY.


Fixing ZIP Files

If an ZIP file is damaged it can sometimes be repaired with the PKZIPFIX command.  Simply type

PKZIPFIX filename

at the DOS prompt, and PKZIPFIX will create the "fixed" file PKFIXED.ZIP.  PKZIPFIX is part of the PKZIP version 2.04 package available from PKWARE.  See the section titled System Requirements for availability.


Archive format

Select an archive format for the archive you are creating.  You can avoid this prompt by selecting from the Default Archive Format field in the Configuration dialog box.


Message WZ10

To create self-extracting archives, first create a standard ZIP, ARJ, or LZH file, then use the Make .EXE File menu entries in the Actions pull-down menu.  While PKZIP, ARJ, and LHA let you create archives with an extension of .EXE, these .EXE files are not self-extracting archives, and attempting to run them can lock up your system.


Message WZ11

A required file was not found.

The file listed in the dialog box was not found in your path or the specified location.  Also, WINZIP.HLP, WZ.DLL, WZ.COM, and WZ.PIF must both be in the same directory as WINZIP.EXE.  The Installation section describes the complete installation procedure.


Message WZ13

This dialog box is displayed if WinZip was unable to open the specified archive, read the archive directory, or if a filename is invalid.  It is possible that the file is not an archive or does not exist.  Alternately, it is possible that the archive has been corrupted.  Other reasons for this error include insufficient memory and disk errors while reading the archive.

If you are working with a ZIP file you can try running the PKZIPFIX program distributed with PKZIP to fix the archive.


Register WinZip

Please enter your name and registration number exactly as they appeared on the instructions you received when you registered WinZip.  You cannot substitute a different spelling for your name or use a different name.  If entered correctly, your name will appear in the About dialog box, and the registration reminder dialog box will no longer be displayed when you start WinZip.  Please save this information for possible use with future upgrades, or in case you re-install WinZip.

Note:  If your name is spelled incorrectly in the instructions, please write to the address in the About dialog box with the correct spelling, and you will receive a new registration number.


Internal Error

This dialog box is displayed when an unexpected WinZip internal error occurs.  Please contact the author with as much information about the error as possible.  For a list of contact points, choose About from WinZip's Help pull-down menu.


Message WZ14

This dialog box is displayed when a required edit field is empty or no entries are selected in a list box.  For example, it is displayed if you don't specify which file you want to open in the Open Archive dialog box.  Specify the required information and try again.


File already exists

To view a file, WinZip normally extracts the file to disk, reads it, and erases the temporary disk file.  WinZip determines which disk to extract to by checking the value of the WZTMP=, TMP=, TEMP=, and PKTMP= environment variables.  To conserve space on the DOS command line, WinZip creates temporary files in the root directory of the specified drive.  If none of these environment variables is set, WinZip extracts to the root directory of your C: drive.

The message The disk file "filename" already exists.  Should WinZip overwrite it so that the file in the ZIP can be viewed? is issued if a file with the requested name already exists on disk.  If you choose Yes, the existing disk file will be overwritten, and processing will continue.  If you select No, WinZip will abort the view operation for this file.


Warning WZ16

This dialog box is displayed if WinZip cannot display the entire file you are viewing because it contains binary zeros.  WinZip uses a standard multi-line edit field to display files, and these controls truncate text at the first binary zero.


Message WZ17

This dialog box is displayed if you try to open a ZIP with a directory too large for WinZip to handle.   You will not be able to open the ZIP file with this version of WinZip.


Message WZ8

This dialog box is displayed if an external command (for example, PKZIP or PKUNZIP)  is over 127 characters long (the longest command allowed under MS-DOS is 127 characters).  The total command line length includes several components used internally by WinZip in addition to the external command.  There are a couple ways to reduce the length of the command line:

1) Move WINZIP.EXE (and the related files) to a directory near the root directory (for example, a directory like C:\WINZIP is better than C:\WINDOWS\UTILITY\SHAREWAR\WINZIP).

2) Move the archive you are working with to a directory near the root directory.

3) Move PKZIP.EXE, PKUNZIP.EXE, LHA.EXE, SCAN.EXE, etc. to a directory specified by your PATH= environment variable and remove any directory names for these programs in the Configuration dialog box.

3) If you are adding, deleting, extracting, or viewing multiple files at one time, specify them via a list box rather than an edit field.  This causes WinZip to create a PKZIP/PKUNZIP, LHA, or ARJ response file, which usually takes less room on the command line than multiple file names.


Selected Text Successfully Copied To Clipboard

This dialog is displayed to let you know the text selected in the View dialog box has been copied to the system clipboard.  You can paste the text into another application (for example, Notepad) by choosing Paste from the application's Edit pull-down menu.


Message WZ18

This dialog box is displayed when WinZip could not create a required temporary file on the disk drive listed in the dialog box.  Possible causes are that the disk drive is invalid, or that the root directory of the disk is full.

WinZip determines which disk to use for temporary files by checking the values of the WZTMP=, TMP=, TEMP=, and PKTMP= environment variables.  To conserve space on the DOS command line, WinZip creates temporary files in the root directory of the specified drive.  If none of these environment variables is set, WinZip creates temporary files on your C: drive.


Message WZ19

When working with format files the "action" operation requires the program external program.  This program is not installed or improperly installed.

This message is issued when the external program "program" required for the "action" operation is either not installed, or is installed in a directory other than the one specified in the Program Locations dialog box.  If the specified program is installed, select Program Locations from the WinZip Options pull-down menu and specify the correct path information.  If you do not have a copy of the specified program, see the section titled Requirements for information on obtaining the program.


Message WZ20

The program required to perform the function you selected is either not installed, or is installed in a directory other than the one specified in the Program Locations dialog box.  For a complete list of supported external programs and information on obtaining these programs see the section titled System Requirements.  Also see the section titled Installing Optional External Programs.

Two examples of why this error can occur are:

1)	To extract files from an ARC file, you need to have specified an ARC extraction program, and the ARC extraction program you specified must exist.

2)	To extract files from password protected ZIPs, or to extract files from a ZIP that spans multiple floppy disks, you need to have installed PKUNZIP, since WinZip's built-in unzipping does not handle these advanced ZIP features.


Message WZ21

WinZip can't find one of the programs specified in the active dialog box.  If you specified a directory (for example, you entered C:\UTILITY\PKZIP.EXE), then WinZip can't find the program in that directory.  If you did not specify a directory (for example, you entered PKZIP.EXE) then WinZip can't find the program in any of the directories specified by your PATH= environment variable.

Note: if you update the PATH statement in your AUTOEXEC.BAT, the changes will not take effect until you reboot your machine.


Message WZ22

WinZip does not recognize the name of the specified program.  For example, you will get this error if you specify UNZIP.EXE as the name for PKUNZIP.EXE.  WinZip lets you specify the drive and directory containing the program, but prevents the use of unsupported file names to prevent unexpected errors.


Message WZ23

An external program returned a non-zero error level.  Consult the documentation for the external program for the meaning of the error, and/or use the View Last Output entry in the Options pull-down menu to check for error messages issued by the external program.

Note: one likely cause for this error is using an old version of external programs. See the section titled System Requirements for version information.


Delete Entire Archive

This dialog box is displayed to give you a chance to confirm that you really want to delete the entire archive.  Select No to abort the operation or Yes to delete the archive.


CheckOut Delete

This dialog box is displayed before closing an archive to give you a chance to have WinZip delete the CheckOut directory and the CheckOut program group.  Select Yes to delete these items and close the archive.  Select No to leave the CheckOut group and directory intact and close the archive.  Select Cancel to cancel the close operation.


Message WZ24

Since most new archives are created in ZIP or LZH format, and there is no single widely available program to manipulate ARC files, WinZip does not provide facilities to create or update ARC files.  WinZip does support viewing, running, and extracting files in ARCs.


Message WZ25

This dialog box is displayed when WinZip cannot run a program.  This can happen when a program specified as a Windows Association was deleted from your system or was moved to a different drive or directory.  The following are the error codes Microsoft has documented:

Value	Meaning

0	Out of memory

2	File not found

3	Path not found

4	Too many files open

5	Attempt to dynamically link to a task

6	Library requires separate data segments for each task

8	Insufficient memory to start application

10	Incorrect Windows version

11	Invalid .EXE file (non-Windows .EXE or error in .EXE image)

12	OS/2 application

13	DOS 4.0 application

14	Unknown .EXE type

15	Attempt in protected (Standard or 386 Enhanced) mode to load an .EXE created for an earlier version of Windows

16	Attempt to load a second instance of an .EXE containing multiple, writeable data segments

19	Attempt was made to load a compressed executable file. The file must be decompressed before it can be loaded.

20	Dynamic-link library (DLL) file was invalid. One of the DLLs required to run this application was corrupt.

21	Application requires Microsoft Windows 32-bit extensions.


Message WZ26

WinZip encountered an error trying to view a file.  Possible errors include insufficient memory and I/O errors.


Message WZ27

An incomplete filename was entered.  If either a drive or subdirectory is specified, then both must be specified.  For example, the following two filenames are incomplete:

C:PKZIP.EXE

\UTILITY\PKZIP.EXE

In the first example, a drive is specified but no subdirectory is specified.  This can cause unexpected errors if you change the current directory on the C: drive.

In the second example, a subdirectory is specified but no drive is specified.  This can cause unexpected errors if you change the current drive.

Specify a filename like C:\UTILITY\PKZIP.EXE instead.  Note that if the file is in a directory specified by your PATH= environment variable you do NOT need to enter a drive and directory.


Warning WZ28

You used the Drag and Drop Interface to drop multiple files onto a WinZip window or icon, and at least one of these files had an extension of ZIP, LZH, ARJ, or ARC.  Press Yes to add these files to the open archive.


Warning WZ29

The original release of Norton Desktop for Windows 2.0 does not accept files dropped by WinZip 4.0.  This means you can't drop files onto the NDW desktop, Desktop Item Icons on the NDW desktop, or NDW group windows.  Future versions of NDW, including a possible update to NDW 2.0, will probably accept files dropped by WinZip.  This dialog box is displayed as a warning that the drop operation may fail because WinZip doesn't know whether files it drops will be accepted by your version of NDW.

The first time you see this dialog box just press the OK button.  The drop operation will continue, and the Extract dialog box will be activated.  After the selected files are extracted, WinZip will attempt to drop the files on NDW.  If NDW does not accept the files, look for an update to WinZip or NDW in the not too distant future.  If NDW accepts the files, select the checkbox labeled "This version of NDW accepts files dropped by WinZip" the next time this dialog box is displayed to suppress display of the dialog box in the future.


Message WZ30

WinZip could not change to the specified directory, so it is closing the open archive.  Possible causes for this error include removing the directory, or changing disks in the middle of a WinZip operation.


Message WZ31

An unexpected system error was encountered trying to run the specified DOS command.  This problem is usually caused by a system configuration problem such as using a Windows 3.0 video driver on a Windows 3.1 system, or using buggy video drivers, including "beta test" video drivers.

If you encounter this error message and are not using a Microsoft supplied video driver, try installing the VGA driver distributed with Windows to determine if the problem is caused by a video driver.  See the section titled Determining Whether a Problem is Caused by a Faulty Video Driver.


Message WZ32

WinZip cannot detect errors issued from NAV unless you have DOS version 4.0 or later.  Either use a different virus scanner or leave the virus scanner edit field blank.


Overwrite?

The specified file already exists on disk.  Choose Yes to overwrite the file or Yes to All to overwrite this file and avoid this prompt for all other files during this operation.  Choose No to bypass this file and continue the extract operation or Cancel to abort the extract operation.


File has been changed

WinZip detected that you modified a file after viewing it.  Choose Yes to add the modified file to the archive or No if you don't want to update the archive.


Warning WZ35

The original file included subdirectory information, but no subdirectory information was included when the file was added to the archive.  Thus, both the original and the new file are included in the archive.


Delete Temporary File?

Choose Yes to delete the temporary file or No if you want to keep it.  Note that the file resides in a "temporary" directory specified by your WZTMP=, TMP=, TEMP=, and PKTMP= environment variables, so you should probably move the file to a "permanent" directory if you really want to keep it.


Warning WZ37

WinZip detected that the Control Panel "Exclusive in Foreground" option is selected.  This option prevents WinZip from running DOS programs like PKUNZIP in the background.  For proper WinZip operation, you must turn off this option.  Under Windows 3.1 you can do this as follows: first double click on the Control Panel icon, then double click on the "386 Enhanced" icon; next, click on the "Exclusive in Foreground" checkbox, and finally push the OK button.


Message WZ38

WinZip cannot accept dropped files while the Drop dialog box is active.  Close the Drop dialog box before dropping more files on WinZip.


Message WZ39

WinZip requires ARJ 2.3 or later.  The date of your ARJ.EXE is earlier than 1/19/91, the date on which ARJ 2.3 was released.  Please obtain a newer version of ARJ.  See the section titled System Requirements for information on obtaining the most recent version of ARJ.


Message WZ40

The ZIP cannot be opened.  If this ZIP is part of a backup set, please insert the last disk of the backup set and try again.  Both PKUNZIP and WinZip need the last disk of the backup set to read the end-of-central-directory record.  You may subsequently be prompted to insert other disks from the backup set.  This is normal PKUNZIP operation and is not specific to WinZip.

If this ZIP is not part of a backup set it may be corrupted.  You can try running the PKZIPFIX program distributed with PKZIP to "fix" the archive.


Message WZ41

This ZIP contains files compressed with PKZIP 2.0.  However, your version of PKUNZIP appears to be older than version 2.0, so the unzip operation will probably fail.  See the section titled System Requirements for information on obtaining the most recent version of PKUNZIP.  See the section titled Built-in ZIP Extraction for a list of reasons WinZip's built-in ZIP extraction is not used.


Message WZ42

The Central Directory for this ZIP spans disks.  This version of WinZip does not handle this situation, so you will have to run PKUNZIP from the DOS command line.  Future versions of WinZip will address this issue.


Message WZ43

PKZIP 2.04C cannot create archives on your A: drive if your current drive is A: unless the PKTMP environment variable is set.  There are two solutions to this problem:

1) Add the command SET PKTMP=C:\ to your AUTOEXEC.BAT and reboot.

2) Use a later version of PKZIP.  This bug has been corrected in both PKZIP 2.04E and PKZIP 2.04G.


Message WZ44

An invalid CheckOut directory was specified.  You cannot specify a root directory (e.g. C:\), and you must specify a drive letter (e.g. C:\CHECKOUT, not just CHECKOUT).  The CheckOut directory cannot be the directory containing the open archive, since all files in the CheckOut directory are deleted at the beginning of the CheckOut operation.


Create Associations

Create File Manager Associations for ZIP, LZH, ARJ, and ARC files?

Answer Yes to this prompt if you want WinZip to create File Manager Associations so that you can start WinZip by double clicking on these files.  If you answer No the installation will continue but you will need to open archives using the Open Archive dialog box or the Drag and Drop interface.


Warning WZ46

PKZIP disk spanning will replace all files in archive.  Continue?

If you choose to continue all files in the archive will be replaced.  PKZIP's disk spanning feature always replaces all files in the archive.  PKZIP does not provide an option to avoid this behavior.


Message WZ47

WinZip could not create the specified directory.  Possible causes are:

•	A file exists with the same names as the directory

•	Disk is read-only

•	Subdirectories preceding the final subdirectory do not exist.  For example, to create the directory "C:\UTILITY\FILES" the directory "C:\UTILITY" must exist.

Solution: specify a different directory name.


Message WZ48

Due to a limitation in the Windows 3.1 Program Manager, it is impossible to remove a Program Manager group while closing Windows.  Thus, if you want to remove Program Manager groups created by WinZip, you need to close WinZip before closing Windows.


Message WZ49

PKZIP does not allow the use of the Freshen and Update options while working with archives that span multiple disks.  You have two choices:

1) Change the Multiple Disk Spanning option to "No Spanning".

2) Use the Add or Move actions instead of Freshen and Update.


Message WZ50

An error occurred opening, writing to, closing, or deleting the specified file.  Possible causes include a misspelled filename, a full disk, a read-only or locked disk, or a read-only or locked file.  The operation in progress will be aborted.  Another dialog box with more specific information may be displayed.

This message may also be displayed because of an invalid archive.  For example, if an archive is damaged (possibly due to line noise while downloading from a BBS) it may contain invalid pointers or corrupted header information.


Message WZ51

The open archive no longer exists on disk.  It was probably deleted by another task.


Message WZ52

Nothing To Do: No files were found for the specified action.  Examples of when this messages is issued include attempts to add a non-existent directory to an archive and attempts to freshen an archive that is already up to date.


Message WZ53

An invalid archive operation was initiated.  For example, an attempt to add the same file from two different directories can cause this error.  Check the warning messages for additional details about the problem.


Message WZ54

This error occurred during internal ZIP processing.  Correct the error and retry the operation.  If you have PKZIP/PKUNZIP installed on your system you can turn off the "Use Internal ZIP and UNZIP" checkbox in the Configuration dialog box to force WinZip to use PKZIP/PKUNZIP instead of the internal ZIP processing.


Message WZ55

WinZip could not access the correct version of the specified DLL.  It is possible that the DLL from a previous version of WinZip is still loaded, or that the wrong version of the DLL is in the WinZip directory.  To solve this problem follow both of these steps:

1)	Verify that the DLL in your WinZip directory has the same date as WINZIP.EXE or WINZIP32.EXE.  If not, reload all WinZip related files from the distribution disk.  DO NOT use WinZip to extract files from BBS distribution version of Winzip to the directory from which you are running WinZip, since that can cause unpredictable results.

2)	Exit Windows and then run WinZip again.  Closing Windows ensures that old versions of the DLL are not loaded.


Message WZ57

There is insufficient free memory (RAM) on your system.  Close one or more other applications and retry the operation.


Warning WZ58

One or more warning messages were issued by the internal zip procedures.  Press the Yes button to view all messages issued while processing the last action, including informational and warning messages.


Virus Scan Complete.

This message is issued when a Windows-based virus scanning operation completes.  If no error or warning dialog boxes were displayed by the virus scanner, then this dialog box indicates that no viruses were found.  The Norton Anti-Virus scanner, the Central Point Anti Virus program, and any other properly configured virus scanner will display error or warning dialog boxes if a virus is found.


Message WZ60

To use the NAVW virus scanner you need the version distributed with Norton Desktop 2.2 or later.  This message is issued if your NAVW.EXE has a date/time stamp prior to January 3, 1993.  Either use a different virus scanner or leave this field blank until a new version of NAVW is installed.


Message WZ61

The open archive does not contain any files that match the filespec you entered in the Extract dialog box.


Message WZ62

WinZip could not copy, delete, rename, or move the file.  Possible causes include: the file is read-only, the file is open by another process, or the file has already been deleted by another process.


Message WZ64

WinZip uses the standard Windows "Common Dialog Boxes" as a basis for the Add dialog box.  Due to a limit in the Common Dialog Boxes the total length of all selected files cannot exceed 2000 characters.  You have exceeded or may exceed this limit.  You can circumvent this limit by using the Drag and Drop interface to add files instead of the Add dialog box, or by specifying wildcards in the Add Files field in the Add dialog box (for example, *.c).


Message WZ65

WinZip could not make the specified directory the current directory.  Probable cause: invalid or non-existing directory name.


Message WZ66

The temporary directory must be a fully qualified path.  You must specify both the drive and directory, for example, C:\TEMP or C:\WINDOWS\TEMP.


Operation Interrupted

The archive operation was interrupted because you pressed a key or clicked on the WinZip window during the archive operation.  Press the Continue button to continue the operation or the Abort button to terminate the operation.

This message will be displayed if you try to minimize WinZip during an archive operation.  To switch to other tasks you can click on another window or use the task list (press Ctrl+Esc).


File Is In Use

A file can be "in use" for one of two reasons:

1)	The file is open by another process.  For example, a document might be open by a word processing application.

2)	The file is "in use" by Windows.  Files that are "in use" are typically programs (.EXE files) or dynamic link libraries (.DLL files) being run by the system.  For example, you will get this message if you attempt to overwrite C:\WINZIP\WINZIP.EXE while running C:\WINZIP\WINZIP.EXE.  The solution is to extract to a different directory, for example, C:\WINZIP5 instead of C:\WINZIP.

WinZip will not let you overwrite or delete a file that is "in use" by the system because this operation could cause unpredictable results, including system crashes.  Windows may read from files that are "in use" at any time, and does not expect these files to change.  If the file has been overwritten Windows will not know the data has changed and can become confused.

If this message is issued during an Extract operation you can either extract the file to a different directory, or retry the operation after closing the program that is using the file.

If this message is issued while WinZip is trying to delete a directory or file you can either continue without deleting the directory or file (and delete it manually later on) or close the file in question and re-try the operation.


Message WZ67

Cannot create filename.  File already exists.  Open existing file?

This message is issued when you press the New button on the toolbar or select New from the File menu to create an archive but the specified archive already exists.  Since the file already exists it cannot be created.  Press the Yes button to open the existing file or the No button to abort the operation.

Normally you should press the Open button to open an existing archive.


Message WZ68

Cannot open filename.  File does not exist.  Create new file?

This message is issued in one of two situations:

1.	You pressed the Open button on the toolbar or selected Open from the File menu and specified the name of a file that does not exist.

2.	You selected a filename from the File menu history list, but that file no longer exists.

Since the file does not exist it cannot be opened.  Press the Yes button to create a file with the specified name or the No button to abort the operation.

Normally you should press the New button to create an archive.


Message WZ69

Due to Windows limitations it is not possible to run two different versions of the same program with the same name at the same time.  As a result, you cannot use WinZip's Install/Uninstall feature to install WinZip.


Message WZ70

This dialog box is displayed when Windows returns a "File Not Found" error when WinZip tries to run another program.  Possible causes include:

1.	A program specified as a Windows Association was deleted from your system or was moved to a different drive or directory.

2.	A required DLL or other component is not installed (e.g. VBRUN300.DLL).


Message WZ71

WinZip could not create a directory because a file (not another directory) with the same name exists.  For example, if a file named "foo" exists you cannot create a subdirectory called "foo" in the same directory.  Choose a different name for the directory you are trying to create, or delete the file with with the conflicting name.


Message WZ72

For seamless integration with WinZip your virus scanner must support automatic scanning.  At the time this version of WinZip was released MWAV does not to support automatic scanning.   Click Yes to continue if you are sure your version of MWAV supports automatic scanning, otherwise press No and select a different scanner.


Message WZ73

WinZip was unable to make the directory displayed in the Add dialog the current diretory.  In some operating environments this can be caused by using UNC names.  Another possible cause for this problem is a conflict with a "common dialog box" enhancement utility.


Caution

The Caution dialog box lists items that cannot safely be uninstalled but were changed during the install process.  These items are unlikely to interfere with a successful uninstall.  For example, a setup program might replace your existing copy of a common dynamic link library like CTL3D.DLL with the latest version of the same library.  In normal situations your existing applications should work with the latest version of the library, so leaving this new version installed will not cause problems.


WZ74

(Win32 only)

This archive contains files with long filenames or blanks.  However, you are using an external archive utility (e.g. PKUNZIP or ZIP2EXE), and external archive utilities don't support long filenames.  Thus some (or all) operations involving this ZIP will fail.  For example, if the archive contains the file "A LONG NAME" and you try to extract it using PKUNZIP or ZIP2EXE the file will be called "A LONG N".


WZ75

The archive does not contain complete filename information, so WinZip cannot determine the full filename of the compressed file.  Replace all or some of the suggested filename with the corrected name and press OK.


WZ76

This compressed file contains a TAR file.  Normally you will want to have WinZip automatically decompress and open the TAR file.  If you choose Yes WinZip will

•	Decompress the TAR file into your temporary directory (as specified in the Options/Directories dialog box).

•	Open the TAR file in the temporary directory.

•	Later, when you close the TAR file in the temporary directory, WinZip will automatically delete it.

Note that the original compressed file is not changed by this operation.


WZ77

This compressed file is stored in the "KWAJ" format introduced after Windows 3.1.  Your copy of the LZEXPAND.DLL or LZ32.DLL cannot handle this compressed file.  The version of LZEXPAND.DLL  distributed with Windows for Workgroups 3.11 works fine, while the old one distributed with Windows 3.1 will not work.  Unfortunately, the LZ32.DLL distributed with initial release of Windows NT 3.5 will not handle these files, and Microsoft has not released documentation on this file format.  You can usually decompress these files with the EXPAND command (from the DOS command prompt enter "expand /?" for instructions).


WZ78

The file you tried to open does not appear to be in the Microsoft Compress (LZEXPAND) format.  Note that not all files ending with an underscore are in the Microsoft Compress format.  For example, some files in the "BBS distribution" version of WinZip have names ending with an underscore but are not in the Microsoft compress format.


WZ79

WinZip could not create or replace the specified ZIP file.  WinZip successfully created or updated the ZIP file in the temporary working directory, but was unable to copy the result to the destination disk.  The most likely cause for this error is a full disk or a write protected disk.  The updated file is left on your hard disk with the specified filename.  After correcting the problem (e.g. freeing up some disk space or removing the write-protect tab from the disk) you can copy the specified filename to the destination disk manually.


WZ80

Please use the 32-bit version of WinZip under Windows 95 and Windows NT.  The 32-bit version is included on the WinZip distribution disk.  The evaluation version of the 32-bit version is available from the WinZip home page (http://www.winzip.com) and on CompuServe in the GO WINZIP file area.


WZ81

At the time of this writing PKZIP and PKUNZIP 2.0 are only available as 16-bit MS-DOS programs.  This version of WinZip only supports these 16-bit versions.  If you have a more recent version of PKZIP it is likely that WinZip has been upgraded to support this new version.  For information on the latest version of WinZip, please send email to info@winzip.com, or download the file winzip.txt from the WinZip file area in the GO WINZIP forum on CompuServe.


WZ82

Apparently PKZIP had trouble detecting a floppy disk change.  There are two known reasons for this:

1.	Running VSHIELD 2.2.2 (from McAfee Associates) under Windows 95 with the /ANYACCESS parameter.

2.	When using multiple disk spanning under some Windows NT 3.51 configurations with the “no format or erase” or “wipe files” options, NT does not tell PKZIP about floppy disk changes.  This problem occurs regardless of whether WinZip is running, and occurs only under NT, not under Windows 95 or Windows 3.1.

General solution: In both cases you can circumvent the problem with one extra keystroke as follows: when the message “Insert Disk 2” is displayed, remove the disk currently in the drive and press the Enter key before inserting the next disk, in other words, press the Enter key with no disk in the drive, rather than after inserting the second disk.  An Abort, Retry, Ignore message will be issued.  Insert the next disk and press the “R” key to continue.

Solution for VSHIELD users: by default, the installation program for SCAN95 inserts a command into your AUTOEXEC.BAT to run VSHIELD with the /ANYACCESS parameter.  If you are comfortable modifying your AUTOEXEC.BAT you can change the /ANYACCESS parameter to /FILEACCESS, and the problem should no longer occur.  Important: do not change your autoexec.bat file unless you have a backup and know how to use it.  Note that you must re-start your computer for this change to take effect.


Association Problem

Some of WinZip's most useful features require that WinZip is associated with ZIP files and other archives.  For more information on associations see the section titled Windows Associations.

It is strongly recommended that you answer Yes to this prompt.

Press the Info button for diagnostic information.


Association Problem Details

This dialog box lists the following information:

Full filename of current WinZip: Note the exact drive and directory information.

Current ZIP Association: this field should include the EXACT name of the "current WinZip" shown above.  If this filename is different it is possible that you have two copies of WinZip installed in different directories.  In this case you will probably want to remove the older copy.

Current Registry value of the ZIP key: This value should be "WinZip".


Association Information

If the Associate WinZip With Archives option is unchecked you will not be able to double click on ZIP files and other archives to open them.  Other features, including the Explorer shell extensions, rely on having WinZip associated with archives.  For more information on associations see the section titled Windows Associations.


WinZip Self-Extractor

Do you need to send files to end users who may not have an unzip utility?  If so, try WinZip Self-Extractor, an optional add-on for WinZip.  WinZip Self-Extractor creates native Windows self-extracting ZIP files.  End users without an unzip program can just double click on a self-extracting ZIP file to unzip it with a familiar Windows interface.  A self-extracting ZIP file is an executable program that includes your ZIP file and a small unzip program (less than 12 kb) that will extract the contents of the ZIP file.  Because no separate unzip program is needed,  self-extracting ZIP files are ideal for sending software, documents, or graphic images to colleagues or clients who may be unfamiliar with data compression.
