Shareaza is a peer-to-peer file sharing client running under Microsoft Windows which supports the Gnutella, Gnutella2, eDonkey Network, BitTorrent, FTP and HTTP network protocols and handles magnet links, ed2k links, Piolet links, and the now deprecated Gnutella links. It is available in 30 languages.
Shareaza can connect to Gnutella, Gnutella2, eDonkey and BitTorrent. Shareaza hashes its files for all networks, and then distributes those hash values on G2. This allows Shareaza to download one file from several networks at once. When another Shareaza client connected to G2 finds such a file, it is given the hash values for all networks and can search on the other networks with their respective hash values, which increases the number of sources and the download speed of the file. Shareaza also uses its G2 network to find more sources for torrents.
Shareaza implements a framework for additional plugins. The Shareaza installer ships several plugins. Most of them are used to read and strip off built in metadata from the files being hashed and convert it to an external XML based format, or to decode multimedia files for making a preview for other G2 clients. Some others serve the need of a media player inside Shareaza, and enhancements of that media player. Third party plugins can also be used, for example, Sharemonkey, which will add a link inside Shareaza when downloading or searching copyrighted material from where it can be legally downloaded.
