CNET editors' review
Reviewed by: Seth Rosenblatt on November 08, 2008
It's easy for Windows users to forget that WinZip isn't the only file-compression utility in the world. Like its better-known competitors, the free 7-Zip unpacks a host of archive formats, including ZIP, TAR, GZ, and its own 7z format. Unlike WinZip, though, it can create TAR and GZ archives, which are commonly used on Unix and Linux systems.
The program's ability to shrink files was stunning. In our tests, 7z archives were up to 40 percent smaller then their ZIP equivalents, although compression did take longer, and the highest compression settings can hog system resources. Advanced options include the ability to create solid and self-extracting archives, and to adjust the compression level and password protection. The program also has a command line module. Though the main interface is overly simple and looks like it was designed for Windows 95, it's not hard to use and fairly self-explanatory. The context menu options, which include "testing" an archive, indicate that 7-Zip should be taken seriously.
7-Zip is fine for casual users with a bit of computer savvy, but it's especially well-suited for developers and anyone else who moves between the Windows and Linux/Unix worlds.

Version: 7-Zip File Manager 4.57
Pros: 7-Zip is free and functions very well. First, its fast, small in size (less than 1MB!), and free! Supports a load of file types, simple and easy to see where the options are when using it.
Cons: Well, the icons aren't very nice, although it is a very small price to pay for something that's free and does a lot more than a lot other paid compression programs do. It also doesn't pack .RAR, sadly. I would love it if it would.
