There are many programs for zipping in net, but I prefer the
7 - zip best, not only its free, but also it has many more features than other zipping software & tools. Its fully open source software & licensed under GNU LGP. It doesnt need the lengthy registration process or activation. It can be used anywhere from home to office.


Among the lots of impressive feature its good part is , like it never shows the long & nasty options in right click menu ; and also has many more options which is the best for zipping and creating archive for mail and other data zipping options.

It has a high compression ratio under its own format, supports many mostly used zipping format, strong encryption. It has strong file manager and command line version.

7 zip is available in 69 languages .
