Scan & Fix 50 registry issues FREECNET Editors' review
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.

"The best FREE file compression software"
Version: 7-Zip 9.20
Pros
Free, User-friendly, Simple, support many archives, support HJSplit files (the .001 .002 .003 etc files), and doesn't make the computer slower.
Cons
Can not click the control buttons when 7-zip is busy archiving or extracting, you must use arrow button and enter button in the keyboard to control it. Sometimes slower, but doesn't matter too much.

"WinZip and a whole lot more!"
Version: 7-Zip 9.20
Pros
Handles ALL major and even not so known compression formats AND its absolutely free! That's IN-SAAAANE!
Cons
GUI isn't as good as WinZip, but it only cosmetic, doesn't interfere with function AND handles more formats than WinZip, WinRAR and WinAce AND there's a portable version for flash drives on www.portableapps.com. Not such a bad trade-off...
Summary
Well don't just stand there! Whaddaya want me to do?!?! Wrap it up in cellophane for ya! Gettin' dere!

Scanned with Ad-Aware, Malwarebytes, and IObit Security 360. Nothing malicious was detected.

It is FREE, why pay for more than I need?Cons
None yet. Worked for me just right.
Summary
Just downloaded this program. Did what I needed (open a RAR file someone emailed to me). It is a very basic program but I do not need all the bells and whistles.
Oh, and BTW. I loaded this on a Windows XP system. No glitches encountered.
