DESCRIPTION:

7-Zip is a free open-source file archiver with a high compression ratio. The program includes both a graphical user interface and a command line interface.

7-Zip offers its own high-compression file format called 7z that is based on LZMA compression, supports AES-256 encryption, and includes self-extraction capabilities. Plus, it supports a number of other compression, and non-compression, archive formats including: ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, ISO, MSI, WIM, NSIS, RPM and DEB. 7-Zip compresses to 7z format 30-70% better than to zip format. The powerful compression program supports volumes of dynamically variable sizes, allowing use for backups on removable media such as writable CDs and DVDs. 7-Zip also comes with its own graphical file manager that allows you to easily and intuitively perform its many functions (copy, delete, extract, add, etc.), as well as access and set options and work with any archived file or sets of files in a folder. Advanced options include the ability to adjust the compression level and password protection. Download it now - you won't be disappointed!
