Extract And Compress Your Files

Extract And Compress Your Files

By:


The 7-Zip interface is similar to that of its competitors, with a main file manager and a command line to search and select files to extract or compress. The control panel is comprised of the essential buttons like extract, add and test, but also features copy, move and delete functions to allow you to manage your files. 7-Zip extracts and compresses files as fast as WinZip and WinRAR and handles the main archive formats like ZIP, TAR, RAR and ISO.

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.

Security is where 7-Zip lags behind its main rivals. There is no option to scan archives for viruses and you cant repair damaged or corrupted files. While you can set a password to protect your archive, you cant choose between different levels of encryption.

7-Zip might not be as secure as WinZip or WinRAR but it is definitely more versatile. It works with more archive formats and offers many useful tools like update mode or splitting. If you feel too limited by WinZip and if you dont like WinRAR we suggest giving 7-Zip a try and taking advantage of all its possibilities.
