7-Zip is a free file-compression utility. The program is able to shrink and unpack 7z, ZIP, GZIP, BZIP2, and TAR and unpacking only is RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB, and NSIS. It is very fast when packing/unpacking files and is much better that alot of the other Zip file managers. And the cool thing I like is that it is supported in 69 different languages. Check out more about 7-Zip or download it from the 7-Zip download page. If you try it out and have any comments about it, let me know.
