WinZip from Nico Mak Computing is a tried and tested file compression and decompression utility which fully supports the Windows name space (long filenames etc.). The free Internet browser support is well worth the brief download - a single click downloads Zip files straight to your default folder from any web page.

Note that WinZip 9.0 Beta is now available for download. Beta versions of Command Line Support Add-On and WinZip Internet Browser Support Add-On are also available.
