7-Zip is a free utility program to help you extract compressed files and create your own compressed files in several different formats. With these tools you can easily send large quantities of information or open compressed files you receive without hassle.
Format options: This program can handle multiple compression formats. It can package files into 7z, ZIP, GZIP, BZIP2, and TAR formats, and it can unpack all those, in addition to ARJ, CAB, CHM, CPIO, DEB, DMG, and more.
Advanced capabilities: This app is straightforward enough that novice users will have no trouble accessing its basic features. But for more advanced users, there are other options as well that make this program even better. These include the ability to create self-extracting 7z files and the option to add password protection to compressed files.
