WinZip
The best way to deal with zip files

If you're going to download programs from the Net, you need a zip program - and WinZip's the best. It sits on your PC as a separate 
program and doesn't 
integrate with your browser 
or work with your Net 
connection in any way. You 
can zip up one file or 
several files into one, more 
compact zip file or archive. 
Conversely, you unzip zip 
files that you've been sent 
or have downloaded from 
the Net to turn them back into useable documents and programs.
