µTorrent (or
uTorrent; commonly abbreviated as "
µT" or "
uT") is a
freeware,
closed source
BitTorrent client owned by BitTorrent, Inc. It is the most widely used
BitTorrent client outside China, where Xunlei is more popular. It gets
the "µ" in its name from the SI prefix "micro-", referring to the
program's small memory footprint: the program was designed to use
minimal computer resources while offering functionality comparable to larger
BitTorrent clients such as
Vuze or
BitComet.
The program has received consistently good reviews for its feature set,
performance, stability, and support for older hardware and versions of
Windows. A report showed that µTorrent is the second most popular
BitTorrent client (after the Chinese Xunlei).
