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.

"Simple, clean interface, and not cumbersome. Do-it-all"
Pros: Simple and clean interface. It does not complicate things. I hate over complicated software that slow down simple tasks. It does all my compress, decompress, archive tasks I need without extra bulk. Plus Free w/o nagging screens.
Cons: Cannot think of any.
Summary: It handles all types of archive/compression formats and tasks that I ever needed. Simply integrates into Windows file explorer operation. It just became seemlessly easy to use. It is free software without nagging screens for donations or registration, or constant update requests. Love it.

"Great archive utility...and free!"
Pros: Free. Knows and manages so many archive formats it's hard to complain at all. All free utilities should be this good.
Cons: I can't think of any cons. I could complain that it's too good to be free.
