An application for a peer-to-peer file sharing system, which was originally developed by Nullsoft but quickly disseminated within the hackercommunity. Like Napster, Gnutella allows users to scan designated folders on other members’ hard drives and copy files of any type between machines. Unlike Napster, Gnutella software doesn’t have a main central database of users.
