Utilities - Compression

7-Zip

Description: An open-source "zip" program. This worked where the others failed on a ....gz.tar file. I didn't find the interface immediately obvious on first try, but because of the success in using it, I'm going to give it some more testing.
License: Open source.

PKZip

Another classic.
License: Pay, but does trial version expire?
