RarZilla Free Unrar can decompress RAR archives. The application is very easy to use, and there’s even a brief explanation about its usage in the main interface. Probably, the easiest way to unpack an archive is by double-clicking it, but this will only work if RarZilla Free Unrar has been set as the default application for that specific extension. However, there are other equally simple procedures, like choosing the Extract option from Windows contextual menu, dropping the file into the program’s window or using the Unrar button to find the needed archive.
All in all, RarZilla unzips RAR files really fast. One of its advantages is that you can create a list of passwords that the program can automatically try when opening the protected archives. However, the downside of creating such a list is that anyone with access to your computer can know what your favorite passwords are. It would have been nice if the program just allowed protecting your lists with another password. In my opinion, the program has a huge limitation: it doesn’t support any other extensions except for RAR and it can’t create archives either.
