qBittorrent 5.2.3

The qBittorrent project aims to provide a Free Software alternative to µtorrent. Additionally, qBittorrent runs and provides the same features on all major operating systems. The user interface is similar to the µTorrent, one of the official BitTorrent client.

This helps ease the transition between µTorrent to qBittorrent for Windows users switching to Linux. qBittorrent is a multi-platform Bittorrent client developed in C++/Qt4 by Christophe Dumez.

Its main features are its integrated search engine. It allows searching for torrent from the main torrent Web sites simultaneously in a transparent fashion.

qBittorrent supports ‘UPnP/NAT-PMP, Bittorrent protocol encryption (Azureus-compatible), Peer Exchange (PeX) compatible with µTorrent, IP filtering (eMule-like “ipfilter.dat” or PeerGuardian filters), Torrents (and the files they contain).
