Universal file archiver – 7-zip

7-zip logoGet rid of WinZip, WinRAR, and stick with 7-zip. Why?

7-zip is pretty much the only file archiver you’ll need, it works with several formats such as: 7z, ZIP, GZIP, BZIP2, TAR, RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB and NSIS. This is an utility I install on every computer I can.

Once installed, you will have a menu of options available when you use your mouse right-click on top of any file. Besides that, if you want you’ll also have the regular 7-zip program you can open and archive or extract files. All of these operations are extremely simple to do.

What is unique about 7-zip? The compression format “.7z”, standard for this program, has a very good level of performance compared to the regular “zip” format. I can even say that its an intelligent compression system because it checks for redundancy in the coding of the files to eliminate unnecessary duplicates. For example, if you have similar files you want to archive – or compact – (two similar programs, text files, etc) 7z will read the coding of the files and compress only the unique coding, removing redundancies. This way you’ll have a very high archiving performance.

Using 7zip format I was able to compact files up to a third of the regular size.

By the way, I almost forgot to tell ya, you can also encrypt your archived files and protect them with passwords.


7-Zip is opensource distributed under GNU LGPL. It works on Linux, Windows, and there is also an unofficial package for MacOS.
