WinZip,
the original and most popular compression utility for Windows, is a
powerful and easy-to-use tool that quickly zips and unzips your files
to conserve disk space and greatly reduce e-mail transmission time.
WinZip 
.2 is available as Standard or Pro.
WinZip .2 is an updated version of our most recent major release—WinZip .0—that supports Windows Vista®.
WinZip .2
offers a thumbnail image view and automatic compression selection, plus
improved compression for audio files (WAV) and the ability to open .BZ2
and .RAR files.
WinZip .2
Pro adds expanded data backup functionality and includes a new internal
image viewer that allows you to browse through multiple images within
the Zip file.
