The WinZip Command Line Support Add-On gives you the power of WinZip without the usual WinZip graphical user interface. Instead, it allows you to use WinZip directly from the Command Prompt (a command line interface), from batch (.bat) files, and from other script languages, making it ideal for automating repetitive tasks. An extensive set of command line options, outlined in the help file included with the add-on, gives you pinpoint control over your zipping and unzipping actions. In automated environments, end-users need not know anything about how to use WinZip.
This add-on to WinZip includes two utilities, WZZIP and WZUNZIP. Both WZZIP and WZUNZIP are fully documented in the WinZip Command Line Support Add-On documentation (help file) that is placed in the WinZip folder when the add-on is installed. You can download the command line add-on from the WinZip website.
If you are not experienced with using a command line interface, but would like to learn more you may want to read some of the information in Command Line Basics.
