OVERVIEW

ZIP files contain other files.  Typically the files in a ZIP file are compressed.  ZIP files make it easy to group files and makes transporting and copying these files faster.

WinZip(TM) is a ZIP file manager for Windows.  It provides an easy-to-use SAA/CUA compatible interface for quickly adding, deleting, extracting, and viewing members of a ZIP file. The program is easy to install, and extensive online help is always available.  All options (including screen size and position) can be saved and restored.

The main WinZip window includes a list of files in the open ZIP file. This list can be scrolled and sorted by name, extension, date, or size.  Files can be added, deleted, extracted, or viewed using pull-down menu entries and push buttons.  The window used to view files in a Zip file can be sized and scrolled.

WinZip supports the CUA "object-action process sequence" philosophy. This allows you to select objects (for example, files you want to extract or view) and then specify the action you want to perform. Alternately, you can use WinZip in a more traditional "action-object" style of interaction.

To start WinZip from the Program Manager, double click on the WinZip icon.  To open an existing ZIP file from the File Manager, simply double click on the ZIP file.

WinZip requires the Shareware PKZIP/PKUNZIP product from PKWARE, Inc.  It runs PKZIP and PKUNZIP in the background in Windows Enhanced (80386) mode, or as full-screen applications in Standard and Real modes.  For more information on this aspect of the program, see the section titled Enhanced, Standard, and Real modes.

WinZip is distributed as Shareware.  This means that users are encouraged, subject to restrictions described in the License Agreement, to share copies of this program with friends, associates and bulletin boards.  Please remember that if you use this software you are required to pay the registration fee of $29 as described in the section titled Copyright/License Agreement/Warranty.

This program is produced by a member of the Association of Shareware Professionals (ASP).  ASP wants to make sure that the shareware principle works for you.  If you are unable to resolve a shareware-related problem with an ASP member by contacting the member directly, ASP  may be able to help.  The ASP Ombudsman can help you resolve a dispute or problem with an ASP member, but does not provide technical support for members' products.  Please write to the ASP Ombudsman at P.O. Box 545 Grover Road, Muskegon, MI 49442 or send a Compuserve message via easyplex to ASP Ombudsman 70007,3536.

PMZIP - An OS/2 PM Version of WinZip
PMZIP - An OS/2 Version of WinZip

PMZIP(TM) is an OS/2 Presentation Manager version of WinZip.  However, PMZIP makes use of some OS/2 features not available under Windows, including threads for faster execution, and support for the File Manager drag and drop facility.  It also features a file search facility to locate selected ZIP files anywhere on a disk.

PMZIP has been available as Shareware since January, 1991 for the same price as WinZip.  Orders for WinZip placed in 1991 will include a free registered copy of PMZIP version 1.0.  Similarly, orders for PMZIP placed in 1991 will include a free registered version of WinZip.

The shareware version of PMZIP can be downloaded from the IBMSYS forum on CompuServe, the IBM.OS2 conference on BIX, and many OS/2 bulletin board systems.

 - Copyright/License Agreement/Warranty

 - Installation

 - WinZip Overview

I also suggest you read the section titled Notes and Background Information for miscellaneous information about the interface philosophy and background, as well as technical notes.  In addition you might be interested in the section PMZIP - An OS/2 PM version of WinZip.

To learn how to use Help press the F1 key or choose Using Help from the Help menu.


Installation
Installation and System Requirements

 System Requirements:

 - Windows 3.0 or later.

 - The PKWARE, Inc.  PKZIP(TM) and PKUNZIP(TM) Shareware programs must be in your path.  You can download these programs from most bulletin boards (the latest version is distributed in the self-extracting ZIP file PKZ110.EXE), or order them directly from PKWARE (phone 414-352-3670).

WinZip-related files are:

 - README.1ST	introductory information

 - WINZIP.DOC	extracts from online documentation

 - WINZIP.HLP	documentation in online hypertext help format

 - WINZIP.EXE	required executable

 - WZ.COM	required executable

 - WZ.PIF	required Program Information File

 - ORDER.DOC	order form

- VENDOR.DOC	information for Shareware Distributors and Disk Vendors

Installation:

 Before running WinZip, follow this one time installation procedure:

1) If you already have installed a previous version of WinZip, delete all files in your WinZip directory.  Otherwise create a directory to hold the WinZip related files.  For example, "C:\WINZIP".

2) Copy all WinZip-related files to this directory.  At a minimum you need the following files:  WINZIP.EXE, WZ.COM, WZ.PIF, and WINZIP.HLP.

 3) Add WinZip to a group in the Program Manager.  This can be done as follows:

a. Open the Program Manager group window for the group you want to add WinZip to.

b. Choose New from the File menu.  The New Program Object dialog box appears.

c.  Select Program Item and choose OK.

d. Type WinZip in the Description text box.

e. Type the full filename of WINZIP.EXE in the Command Line text box.  For example, C:\WINZIP\WINZIP.EXE.

f.  Choose OK.

You can then start WinZip by double clicking on the WinZip icon in the program manager.  You can open an existing ZIP file from the File Manager by simply double clicking on any ZIP file.

Note: a File Manager association for files with an extension of "zip" is set up automatically to make it possible to start WinZip by double clicking on a Zip file.

File Menu
The File Menu

You can open ZIP files with the standard New or Open entries on WinZip's File pull-down menu.  These functions work like those of most other Windows applications.  You can also open a ZIP file listed in the File Manager by double clicking on the ZIP file (this starts a new instance of WinZip).

You can close the current ZIP file with the Close entry on the File pull-down menu.  However, this menu entry is included primarily for completeness, since the New and Open dialog boxes automatically perform this action.

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

The Exit menu entry exits (closes) WinZip.


Adding files to a ZIP file

There are two ways to add files to a ZIP:

1) Click on the Add push button or select the Add entry from the Action pull-down menu to bring up the Add dialog box.  Then specify the file names you want to add.  Standard MS-DOS wildcards are accepted, and multiple file names can be specified.

2) Click on the Add push button or select the Add entry from the Action pull-down menu to bring up the Add dialog box.  Then click on the Select Files push button.  This expands the Add dialog box.  You can then select files from an Extended Selection List Box.  The expanded Add dialog box works much like a standard Windows Open dialog box.

If you would like WinZip to automatically expand the Add dialog box , click on the Unfold check box before clicking on the Add button, and save your current settings with the Defaults dialog box (available from the Options pull-down menu) before closing WinZip.

The Add dialog box provides the following options:

 - The Add, Freshen, and Update radio buttons correspond to the PKZIP -a, -f, and -u options

 - The "delete original after adding" check box corresponds to the PKZIP -m option

 - The Size and Speed radio buttons correspond to the PKZIP -ex and -es options

 - The "Recurse subdirectories" check box corresponds to the PKZIP -r option

 - The "Store recursed pathnames" check box  corresponds to the PKZIP -p option

 - The "Store specified pathnames" check box corresponds to the PKZIP -P option


Deleting files from a ZIP file

There are two ways to delete files from a ZIP:

1) Object-action interface:  first select entries in the list box, then click on the Delete push button or select the Delete entry from the Action pull-down menu.

2) Action-object interface:  click on the Delete push button or select the Delete entry from the Action pull-down to bring up the Delete dialog box.  You can then specify the file names you want to delete (standard MS-DOS wildcards are accepted).


Extracting files from a ZIP file

There are two ways to extract files from a ZIP:

1) Object-action interface:  first select entries in the list box, then click on the Extract push button or select the Extract entry from the Action pull-down menu to bring up the Extract dialog box.

2) Action-object interface:  click on the Extract push button or select the Extract entry from the Action pull-down to bring up the Extract dialog box.  You can then specify the file names you want to extract (standard MS-DOS wildcards are accepted) or extract all files in the ZIP.

The Extract dialog box lets you specify the directory to contain the extracted files (note: the default directory for this prompt can be changed by selecting "Extract Directory..." in the Options pull-down menu).

The Extract dialog box provides the following options:

 - The "Overlay newer files only" check box corresponds to the PKUNZIP -n option

 - The "Use pathnames" check box corresponds to the PKUNZIP -d option

Note: the PKUNZIP -o option is always specified.


Viewing files in a ZIP file

There are three ways to view files in a ZIP file:

1) Double click on a file name in the list box listing files in the ZIP file.

2) Object-action interface:  first select entries in the list box, then click on the View push button or select the View entry from the Action pull-down menu.

3) Action-object interface:  click on the View push button or select the View entry from the Action pull-down to bring up the View dialog box.  You can then specify the file name you want to view.

The View dialog box is used to view files in a ZIP file or view the results of the last PKZIP or PKUNZIP command issued by WinZip.  Unlike most dialog boxes, the View dialog box is sizeable and can be maximized.

If you've selected multiple files for viewing, click on the Next push button to view the next selected file.

Click on the Clipboard Copy push button to copy selected text to the system clipboard.  Note: this button is disabled when no text is selected.


Options

The WinZip option system consists of the following components:

The Option pull-down menu lets you specify whether the list of files in the ZIP file is sorted by date, extension, size, name, or whether the original ZIP file order should be used. It also lets you bring up the following dialog boxes described below.

The Configuration dialog box lets you specify

 - Whether the default directory in the Extract dialog box is the current directory or a directory of your choice.

 - Whether files in the ZIP file are listed in lowercase for the possibility of improved legibility.

 - Whether WinZip should maintain a log of all error messages and all PKZIP and PKUNZIP commands it issues. The log is written to the file C:\WINZIP.LOG.

The Defaults dialog box lets you save the current defaults for use next time WinZip is started, or restore the original distribution defaults.  Options that are saved and restored by this procedure 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.

The View last output entry in the Options pull-down displays the results of the last PKZIP or PKUNZIP command issued by WinZip.


Enhanced, Standard, and Real Mode

In Windows Enhanced (386) mode PKZIP and PKUNZIP commands issued by WinZip to update your ZIP files are executed in the background in an iconized DOS session.  While these commands are running you can switch to another window.  An hourglass pointer is used to indicate that the WinZip window is busy.  You can double click on the icon titled "WinZip running PKZIP/PKUNZIP" to monitor the command's progress.

Unfortunately, it is impossible to execute the PKZIP and PKUNZIP commands in the background under Standard and Real modes.  In these modes your screen will be cleared, and PKZIP/PKUNZIP commands will be run in a full screen DOS session.

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

Your Windows 3.00 User's Guide contains descriptions of Enhanced, Standard, and Real modes.  You can determine which mode is active by choosing About in the Program Manager's Help pull-down menu.


Error Handling

WinZip does not manipulate ZIP files directly.  Instead it runs the PKZIP command for all operations that update ZIP files.  Thus it is highly unlikely that WinZip will ever cause a corrupted ZIP file.  If you suspect a corrupted ZIP file, issue following command from a DOS prompt:

pkunzip -t filename.ZIP

If PKUNZIP reports that your ZIP file is damaged, try the PKZIPFIX command, as documented in section 5 of your PKZIP manual.

When a PKZIP or PKUNZIP command issued by WinZip returns a non-zero error level, a dialog box is displayed listing the error level and error level description.  Click on the "View last output" button to view all messages issued by the command that caused the error.

WinZip will optionally maintain a log of all error messages and all PKZIP and PKUNZIP commands it issues. The log is written to the file C:\WINZIP.LOG.

If you encounter errors in WinZip, please report them (see the section Support and questions for information).


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 Open new Zip file.

Ctrl+O Open existing ZIP file.

Ctrl+A Add files to a ZIP file.

Ctrl+D Delete files from a ZIP file.

Ctrl+E Extract files from a ZIP file.

Ctrl+V View files in a ZIP file.

Ctrl+Slash (/) Select all items in the list box.

Ctrl+Backslash (\) Cancel the selection of all items in the list box.

Direction key(s) Move the cursor or  scroll to other items in the list box.

Shift+direction keys Select multiple items in list box..

Shift+F8 Toggle "add mode" on and off.  When add mode is on, you the selection cursor blinks.  In this mode you can use the Spacebar to select nonconsecutive items in the list box or to cancel the selections.  Press Shift-F8 again to end add mode.


Using Extended Selection List Boxes

WinZip uses Extended Selection List Boxes for the list of files in a ZIP file and for the list of files in the Add dialog box.  You can select files from an Extended Selection List Boxes the same way as you select files in the File Manager, with one important difference: in an Extended Selection List Box you can select multiple files by clicking on the first file, and while holding down the mouse button, drag over other files you want to select.

To select an individual file in an Extended Selection List Box, click on the file.  This cancels all previous selections.  To select additional files, hold down the Ctrl key while clicking on the files.  To select a group of files and cancel all previous selections, click on the first file, and while holding down the left mouse button, drag over other files you want to select.  To select additional groups of files, hold down the Ctrl key, click on the first file in the group, and while holding down the left mouse button, drag over the other files you want to select.  You can use the Select all and Deselect all entries in the File pull-down menu to select and deselect all files in a ZIP.

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


Future Enhancements
Ideas for future enhancements

Ideals for future enhancements include:

- Support for other file formats (e.g. ARC, ZOO, and LHZ)

 - Support for all ZIP options, including passwords and comments

 - Ability to run programs in a ZIP file

 - Optional hex and ASCII  dump mode when viewing files in a ZIP File

 Additional suggestions from all users are welcome!


Notes and Background Information

 - This version of WinZip was tested under Windows 3.00 with PKZIP and PKUNZIP versions 1.1.

 - PKZIP and PKUNZIP are registered trademarks of PKWARE, Inc.

- There is a bug in Windows 3.0 that can cause Windows to crash if you try to update a read-only disk.  This can occur if you attempt to update a ZIP file on a read-only disk with WinZip.  Microsoft Online technical support has stated that this is a known problem, and that no workarounds are available for Windows 3.00.  You can demonstrate this problem in Enhanced mode without WinZip as follows (be sure to save your files first):

- Start a DOS session from the Program Manager.

- Try to delete a file on a read-only disk.  Reply Abort or Fail to the critical error message.

- Exit the DOS session.

- Try to access the read-only file from a Windows application (e.g. Notepad).

At this point Windows typically locks up or terminates.

- You can change the default WinZip icon as follows:

a. Open the Program Manager group window for the group containing WinZip.

b. Choose Program Properties from the File menu.  The Program Item Properties dialog box appears.

c. Click on Change Icon.  The Select Icon dialog box appears.

d. Click on View Next to cycle through the icons.  Choose OK when your preferred icon appears.

e.  Choose OK.

 - WinZip supports most commonly used PKZIP and PKUNZIP options but the current version does not include special support for comments, passwords, and file attribute masks.

 - WinZip uses temporary disk files to communicate with WZ.COM and the PKWARE, Inc. programs.  WinZip uses a unique filenames for these files, and automatically erases them when they are no longer needed.  WinZip determines which disk to use by checking the value of the WZTMP=, TMP=, TEMP=, and PKTMP= environment variables.  If none of these environment variables is set WinZip uses the root directory of your C: drive.

- WZ.COM is used for two reasons: to obtain the error level (return code) from the PKZIP and PKUNZIP commands, and to capture the output from these commands for use by the "View last output" entry in the Options pull-down menu,

 - WinZip is a Windows version of PMZIP.  I wrote PMZIP because I wanted an OS/2 Presentation Manager  interface to ZIP files, and no other programs provided this facility.  The first version was written in Digitalk's Smalltalk V/PM.  The result, like all V/PM programs, required over a megabyte of code to execute, and was rather slow.  Favorable response to the first version convinced me to rewrite the program in C and release it as Shareware.  I subsequently rewrote it for Windows, and this is the result.

- Special thanks to Steve Queen for his  feedback on the WinZip user interface.


Missing file(s)

A required file was not found.

PKZIP.EXE and PKUNZIP.EXE must both be in your path.  Also, WINZIP.HLP and WZ.COM must both be in the same directory as WINZIP.EXE.  The Installation section describes the complete installation procedure.


Invalid ZIP File

This dialog box is displayed if WinZip was unable to open the specified ZIP file, read the ZIP file directory, or if a fileid is invalid.  It is possible that the file is not a ZIP file.  Alternately, it is possible that the ZIP file has been corrupted.  For more information, see the section titled Error Handling.


Add files selected in list box?

This dialog box is displayed if you've updated the edit field in the expanded Add dialog box after selecting files from the list box.  WinZip isn't sure whether you want to add the selected files or add the files that match the names specified in the text field.  To add the selected files click on the OK button.


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.


Missing Input

This dialog box is displayed when a required edit field is empty.  For example, it is displayed if you don't specify which file you want to open in the Open dialog box.  Specify the required information and try again.


No files selected in list box

This dialog box is displayed if you click on the Add button in the expanded Add dialog box but haven't selected any files to add.  Select one or more files in the file list box, or click on the Cancel button.


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.  If none of these environment variables is set it extracts to the root directory of your C: drive.

The message The disk file "fileid" 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.


Text truncated at first binary zero

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.


ZIP Directory Too Big For WinZip

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.


ZIP Command Too Long

This dialog box is displayed if  a PKZIP or PKUNZIP command is over 128 characters long (the longest command allowed under MS-DOS is 128 characters).  The total command line length includes several components used internally by WinZip in addition to the PKZIP or PKUNZIP 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\UTILITIES\SHAREWARE\WINZIP).

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

3) If you are adding, deleting, extracting, or viewing multiple files at one time, specify them via a listbox rather than an edit field.  This causes WinZip to create a PKZIP/PKUNZIP 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.


Could Not Create Temporary File

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.  If none of these environment variables is set, WinZip creates temporary files on your C: drive.
