WinZip is one of those ubiquitous compression programs that nearly everybody has on their computer, although there are many other rival products available.

Compressing files that are destined to be distributed over the Internet greatly reduces the time taken to download them. Also, storing compressed files saves on hard disk space. WinZip, as the name implies, primarily relies around ZIP technology, which is now supported within both Windows and Mac OS as their default choice of compression.

This is the latest WinZip 12. New features include the ability to compress photos (stored within a ZIP) file by as much as 25%. WinZip 12 now has the facility to work more effectively within ZIP files, so you can manipulate and edit files, without extraction. You can now work with 7z, ISO and IMG files and the Professional version now enables you to create various user passwords to control access.
