This one is a real crock. I really like IZArc (http://www.izarc.org/), the free zipping utility that Pat recommended. It is much more powerful than WinZip. The problem is that WinZIp cannot be uninstalled without its throwing a temper tantrum. Even if you uncheck associating zip file with the program, you still get the warning that it will remove all zip files from your computer when you start to uninstall, sort of like, "I am going to take my toys and go home.." ;D I don't know if that is true, but I cannot risk it.
