WiZ is a graphical front end for Zip and UnZip; its primary author is Mike White. WiZ currently runs only under 32-bit Windows (95/98/ME/NT/2000/XP/etc.), although older releases also supported 16-bit Windows 3.x. As with all of Info-ZIP's software, WiZ is completely free and available as source code, too. Groovy.
Note that a similar graphical port for the Macintosh, MacZip, is also available.

Ready-to-run binary versions of WiZ are available for 16-bit Windows 3.x and for 32-bit Windows 95/98/ME and NT/2000/XP (including Alpha). See below for detailed installation instructions.
(This section was provided by John Coombes.)
Important Note: DO NOT double-click on wiz401x.exe while it is still in your download directory, as it is a self-extracting executable -- that is, it is NOT self-installing. If you do, it will extract itself into the download directory.
Info-ZIP's 16-bit version of WiZ is for use with Windows 3.1 or 3.11. It is compatible with PKZIP 2.04g, and it can zip, unzip and make self-extracting EXE files.
All instructions assume that you are doing the installation from within Windows 3.x and not directly from DOS.
Add C:\WIZ to the end of it so it looks like this:
You must put in a semicolon (;) just before you put in C:\WIZ .
Or you can use SYSEDIT: from Program Manager go FILE, RUN and type in SYSEDIT and click OK. Up will pop a window with various system files that you can edit. Only edit AUTOEXEC.BAT (as above); then from the SYSTEM CONFIGURATION window go FILE and click SAVE before you click EXIT.
Now you are finished; you can use WiZ by clicking on its icon.

Important Note: DO NOT double-click on wiz503xN.exe while it is still in your download directory, as it is a self-extracting executable -- that is, it is NOT self-installing. If you do, it will extract itself into the download directory.
Info-ZIP's 32-bit version of WiZ is for use with Windows 95, Windows 98 or Windows NT 3.5 and later. It is compatible with PKZIP 2.60, and it can zip, unzip and make self-extracting EXE files.
All instructions assume that you are doing the installation from within Windows 95/98/NT and not from the DOS 7.x command line.
Now you are finished; you can use WiZ either by clicking on its icon or by double-clicking on any zipfile. Unlike the 16-bit case, there is no need to reboot the computer to enable the 32-bit version of WiZ.
The DLL source code for Zip and UnZip is required to compile WiZ; it is available either in the full source archives for Zip and UnZip or as part of the wiz503.zip combined source archive. (Encryption and decryption are now enabled by default, so no extra steps are required for that.)
