Winrar is a free app that lets you compress and unpack any file in a very easy, quick and efficient way. The program integrates itself perfectly in the right-button menu, so you can easily create RAR and ZIP files. You can also add a password or a comment.
Regardless of the compressed file’s format, you can unpack more than 40 different formats, including CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, RAR, Zip or 7Z. Just double-click the icon and the content of the file will appear on the screen. Then, choose whether to unpack it or run the files without having to unpack it previously.
Plus, Winrar offers a very good compression ratio (above the average), which means that the files you compress will be smaller than compressing them using other programs. Finally, you can also protect files using Rijndael (AES-128) encryption system, digital signature or protect it against modifications. Winrar is probably the best compression tool out there. The countless number of options, as well as its versatility and ease, make it a must-have for any user.
