Extracts file from RAR, ZIP, ARJ, 7z and other types of archives. Creates regular, multi-volume and secure archives. Its own compression algorithm (7z) is stronger than RAR or ZIP.

Based on the LZ77 algorithm, both LZMA and LZMA2 compression techniques provide an excellent data compression ratio. 7-Zip uses these compression methods to create archives in the 7z format protected with AES-256 encryption, though it supports any compression, conversion, and encryption method. It can also create ZIP, TAR, WIM, GZIP, BZIP2, and XZ archive files, and unpack an even wider range of formats, including RAR, ARJ, ISO, or DMG.

At the top of the list of the open-source data compression tools available, and usually, among the five best archive tools of all kinds (commercial products included), 7-Zip has become one of the most widely used utilities to pack and unpack not only its own archives but also most of the most commonly used ones. Its high speed and its incredible compression ratio, together with its unbeatable price, make it a serious contender to WinZip and WinRAR. ZIP files are not a problem for 7-Zip, which can not only create new ZIP archives but also extract files from them. As for RAR, only WinRAR can create new archives, but 7-Zip can easily unpack or decompress any RAR files. In both cases, 7-Zip can be up to 10 percent faster than any of them. more

Thank you for putting something out easy to use for folks that don't under all there in to know about compressing files. A great program for those that do. Also WinZip and WINrar are not making money on it.
