How can I use the Command Line feature in WinZip?
In order to use command line in WinZip, you need to install the WinZip Command Line Add-On available here for free for all registered users:
http://download.winzip.com/ov/wzcline11.exe - for WinZip 9
http://download.winzip.com/ov/wzcline22.exe - for use with WinZip 10.0, 11.0, or 11.1 (Pro Only)
http://download.winzip.com/ov/wzcline23.exe - for use with WinZip 11.2
Download the file, run it and follow the on-screen instructions.
Note: There will be no uninstall feature for this add-on, which means you'll have to manually remove the files if you want to uninstall it (located usually in C:\Program Files\WinZip).
