MLdonkey is a multi-platform multi-networks peer-to-peer client. It was the first open-source client to access the eDonkey network. Today, MLdonkey supports several other large networks, among which Overnet, Bittorrent, Gnutella, Gnutella2, Fasttrack, Soulseek, Direct-Connect, and Opennap.
MLDonkey was the one which introduced a method to connect to several servers simultaneously years ago, when server weren’t so powerful like nowadays.
Like that, it now includes some features not included in other P2P clients. It is a good choice when filesharing videos, photos, docs or whatever.
