Compressed files take up less space and therefore they are often found on the Internet as their transmission lasts much shorter than uncompressed files. Are you looking for a completely free tool to help you work with this type of file, 7-Zip could be the right choice. Except that it supports all popular compression formats like ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB, 7-Zip has its own 7z format with which the files can be summed up 30-50 percent more than using conventional ZIP compression. Like most tools of this kind of 7-Zip supports the context menu (menu that appears when you right-click on a file). All you need to uncompress a file using 7-ZIPA is click on it by right mouse button and choose the option Extract to - the directory name. All in all excellent, and even how a free tool that is localized to as many as 60 languages. Congratulations to the author holds that this product is still free, a program that you at least try it and faith in the quality thereof....
