Editor's review of 7-Zip 4.23
4.0 stars
- "Zip this"
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 4.23
Pros: Works with non-standard ZIP and RAR files that don't work with WinZip or WinAce.
Cons: It would be nice if there was a back button on the toolbar, and the program supported drag and drop opening. The program is still good though!

Version: 7-Zip 4.23
Pros: It is small and fast.
Very reliable, as long as i can remember it can manage huge compression almost 1Gigs.
It is free.
It is improving as long as the version. Nice job!
Cons: 2 homeworks yor 7-zip.
1. The interface.
2. Drag&Drop rulez! Dont forget about this one, okay it is improving from the old version, but it not enough.
I can't add a folder to my old archive. It gives me some eror notes.
I can't select all files in archieve by my mouse, must use my keyboad.
