An application for a
peer-to-peer file sharing system, which was originally developed by Nullsoft but
quickly disseminated within the
hacker community. 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.
