xTorrent Toolbox — A user should install and run at least once any of the supported products before executing this tool. If a user launches the tool on a system without any installed product, it will ask him to select the folder where the target program files are located. A user can skip this message selecting «No», and then use the «Refresh» button at any time to detect it/them, once the user installs the program(s).

BitTorrent is a peer-to-peer file sharing (P2P) communications protocol. BitTorrent is a method of distributing large amounts of data widely without the original distributor incurring the entire costs of hardware, hosting and bandwidth resources.
