BitTorrent Smart is a convenient tool for downloading and distributing very large files. It is based on BitTorrent technology, so if a server receives many download requests for a given file at once, it makes downloading users to automatically send pieces of file to each other thus relieving the central server's bandwidth burden and increasing download speed. It uses bandwidth optimization and control system and allows downloading multiple torrents at the same time with the possibility to set download priority. Even with many simultaneous downloads, the upload burden on the central server remains quite small, because every new downloader introduces new upload capacity.
