7-Zip is all I use now! I love it. If you try to take my 7-Zip away from me you will leave in a body bag!

Seriously, it is a great little program. Before I started using it, I used WinZip and WinRar. I finally got fed up with WinRar because of all those stupidly annoying nag screens that tell me I am using a shareware version. Once I started using 7-Zip I never looked back. It is so easy to use and laid out very nicely. Give it a try. Once you try it, you won't want to go back to anything else.
