One product which has really impressed me is 7-Zip. It can unpack a multi-part RAR volume embedded in a ZIP archive, and gives a meaningful error message when attempting to unpack a 256-bit encrypted WinZip archive.
7-Zip supports 7z, zip, gzip, bzip2, tar, arj, cab, chm, cpio, deb, dmg, hfs and much more. It has a strong AES-256 encryption in 7z and ZIP formats and has powerful integration with Windows Shell.
Even though it handles fewer archive types than some other programs, it is a fantastic program that will fulfill 99% of all your file archiving needs.
There is a port of the command line version to Linux/Unix available at the link provided above.
