>Does it support "winzip -u zipfile @listfile.txt"? That's the feature I've been missing ever since we went Windows, and the primary reason I kept zipping in an invisible DOS task. I have strict rules what gets archived with what - my slogan is always "ours the app and yours the data - everyone take care of his own stuff", so I maintain two lists, app files to get archived when I need to port the project to another development machine, and user files to get regularly archived from within the app.

Hi Dragan,
Yes it does, although it's a slightly different name
This single batch file command backs up all my development in minutes, to the file name supplied as a parameter. Beats the heck out of MS Backup

wzzip -a+ -rP -s"My long password" %1 @include.txt -x@exclude.txt

This does an incremental....

wzzip -i -rP -s"My long password" %1 @include.txt -x@exclude.txt

Of course there's a WZUNZIP as well

HTH
