qBittorrent is a light file sharing utility. Although the end product of a volunteer-based project aimed at promoting free software alternatives to paid solutions, it integrates a wide variety of features into a nicely polished interface.
Among them, one can emphasize the possibility of performing a simultaneous search in the most important torrent sites and categorizing results according to given requests.
Downloads can be optimized through sequential ordering, bandwidth management, and port forwarding. Similar to other file-sharing software, web remote control and RSS feeds are also provided.
Undoubtedly important for such a program is the integration of a torrent creation tool and the IPv6 compliance.
