Winrar is probably the best compression tool out there. Finally, you can also protect files using Rijndael (AES-128) encryption system, digital signature or protect it against modifications. 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. Then, choose whether to unpack it or run the files without having to unpack it previously. Just double-click the icon and the content of the file will appear on the screen. 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. You can also add a password or a comment. The program integrates itself perfectly in the right-button menu, so you can easily create RAR and ZIP files.
