Much like ZIP files, RAR files are a type of compressed archive file that allows users to transmit large amounts of data in a more compact format. Also like ZIP files, RAR files need special software to be opened. RAR File Open Knife - Free Opener is a basic RAR utility that lets users open RAR files quickly and easily.
The program's interface is basic and a little goofy, featuring a large image of a knife with an ornately carved handle. To un-RAR a file, users simply drag and drop the file onto the program's interface, right-click the file to access RAR File Open Knife from the context menu, or double-click the file to start RAR File Open Knife automatically. The program worked just fine, quickly unpacking everything we threw at it. The built-in Help file is quite lengthy and is really just an unorganized FAQ, although it does provide plenty of information about RAR File Open Knife and RAR files in general. There's even a link to a video tutorial. Our only real complaint about the program was that it's being used as an advertising vehicle for its creator's other projects; three tabs in the interface labeled Gifts, Thanks, and Appreciation contain links to screensavers, e-books, and wallpaper. Although all of this is free, it takes up more space in the program's interface than the program's actual features do. A less cluttered and more professional interface would be an improvement.
RAR File Open Knife installs and uninstalls without issues. We recommend this program to all users.
