Very good, easy to use and more user friendly than WinZIP.

I prefer this software over WinRar only because it is so easy to use and it is open source. It works well on windows Xp Home.

This is so much better than WinZip or WinRar, because it has a better compression ratio, support for more file types, and a smaller download. Plus it's free and open source! It is updated regularly and I have been using it for two years now and have never had a crash or other problem. A must-have!
