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.

WinRAR is a lightweight, flexible, and easy-to-use archiving utility that can unpack most archive formats, as well as compress to both RAR and ZIP. Free to try for 40 days ($29 for single license), WinRAR is definitely top dog in the compression category.

WinRAR's interface is about as simple as it gets. Start creating (or add to) an archive by dragging and dropping your files into the interface or by browsing through the Folder Tree side panel (when enabled). From there, the most common functions are laid out in the form of colorful, mostly intuitive icons, which can all be customized by downloading themes from the company's Web site. Add files to, Extract, Test, Delete, or even Repair archives right from the main interface. Drop-down menus house the program's more advanced features, including self-extracting archives, archive locking, benchmarking, and autodeletion of temp files.

In our performance tests, both creating and unpacking archives was blazingly fast. Compression ratios varied depending on file type, but in general seemed on par with or slightly better than other archiving programs. Overall, WinRAR is a winner because of its speed, simple interface, flexibility with file formats, and powerful advanced features.
