From the developer: "Cheetah is a Kazaa/Grokster (Fasttrack) efficiency tool. It does not compete with other network accelerators. Several of its features include automatically searching for more sources when a download has stalled, removing duplicates in your download list, removing files from the download list which are already on your computer and giving you the option to remove files you?ve previously downloaded even if they are no longer on your system so you don?t have to check them out twice.?
