Its main features are:
- Upload speed capping, seeing that most people can't upload infinite amounts of data.
- Internet searching using, among others, The BitTorrent website's search engine (using Konqueror through KParts).
- Support for UDP trackers (UDP Tracker Protocol).
- The ability to choose which files in a BitTorrent archive will be downloaded by the client.
To make KTorrent the default program for torrents, click a torrent link, and open it with /usr/bin/ktorrent (KDE 4) or /opt/kde3/bin/ktorrent (KDE 3)
