µTorrent is an efficient and feature
rich BitTorrent client for Windows sporting a very small footprint.
µTorrent was designed to use as little cpu, space and memory as
possible while offering all the functionalites expected from advanced
clients. With BitTorrent, you can download files faster and contribute
by sharing files and bandwidth.
Most of the features present in other BitTorrent clients are
present in µTorrent, including bandwidth prioritization, scheduling,
RSS auto-downloading and Mainline DHT (compatible with BitComet).
Additionally, µTorrent supports the Protocol Encryption joint
specification (compatible with Azureus 2.4.0.0 and above, BitComet 0.63
and above) and peer exchange.
µTorrent
was written with efficiency in mind. Unlike many torrent clients, it
does not hog valuable system resources - typically using less than 6MB
of memory, allowing you to use the computer as if it weren't there at
all. Additionally, the program itself is contained within a single
executable less than 270 KB in size.
Various icon, toolbar graphic and status icon replacements are
available, and creating your own is very simple. µTorrent also has
support for localization, and with a language file present, will
automatically switch to your system language. If your language isn't
available, you can easily add your own, or edit other existing
translations to improve them!
The developer puts in a lot of time working on features and making
things more user-friendly. Releases only come out when they're ready,
with no schedule pressures, so the few bugs that appear are quickly
addressed and fixed.
