qBittorrent is a free and convenient torrent client, with certain problems you should consider.
Features: Supports DHT, Peer Exchange, Full encryption, Magnet/BitComet URIs, … * Remote control through a Web user interface * Advanced control over trackers, peers and torrents * Torrents queuing and prioritizing * Torrent content selection and prioritizing * UPnP / NAT-PMP port forwarding support * Available in ~25 languages (Unicode support) * Torrent creation tool * Advanced RSS support with download filters (inc. regex) * Bandwidth scheduler * IP Filtering (eMule and PeerGuardian compatible) * IPv6 compliant
qBittorrent won’t install anything except for the program itself.
Don’t forget to enable the Speed in Titlebar option (from the “View” menu), if you want to see the upload and download speeds on the titlebar of the program – and on the Windows Taskbar. (If you use Windows 7 and the taskbar shows only icons, get Taskbar Labels to enable text beside the taskbar icons.)
Note that qBittorrent, like most of the available torrent clients, will drain the resources of your system if you download several torrents together, causing trouble especially to media players like Winamp.
Note also that the user interface at times requires necessarily mouse input (qBittorrent is not always controllable with the keyboard).
Sometimes a torrent may turn by itself to pause status!, and there is not even an auto-resume feature.
The search included in qBittorrent can not perform an exact match search – you will get far more (and irrelevant) results than what you asked for according to your keyword.
