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.
