WinRAR

WinRAR is a powerful compression tool with many integrated additional 
functions to help you organize your compressed archives.

WinRAR puts you ahead of the crowd when it comes to compression. By 
consistently creating smaller archives, WinRAR is often faster than the 
competition. This will save you disc space, transmission costs AND valuable 
working time as well.
WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, 
ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip)
