The official BitTorrent client for file sharing.
This free, open source file-sharing application is effective for distributing very large software and media files.
With BitTorrent, those who get your file tap into their upload capacity to give the file to others at the same time. When you download a file, BitTorrent trades pieces you have with pieces your peers have. Those that provide the most to others get the best treatment in return. Supports resuming downloads and multiple downloads.
You will notice that BitTorrent 6 comes with BitTorrent DNA, which stands for Delivery Network Accelerator.
BitTorrent DNA is an enterprise-grade content delivery accelerator. It is distributed by your favorite websites and software companies to speed up your downloads by connecting to multiple sources of the same file. During and after each download, your computer helps distribute what you download. By giving and receiving in this way, your favorite websites operate more efficiently and provide a better and faster experience for everyone.
