Limewire is a free file sharing program, which allows individual users on the Internet to make music, video and other files available for direct access by other users. Limewire also allows a user to search for desired content on other users' computers and download those files.

Unlike the now-defunct Napster, no centralized server or website is used to store files. Limewire directly transfers files from the hard drive of one user (peer) to the hard drive of another user, hence the term "peer-to-peer" or P2P file sharing is used. Given that understanding, it's more accurate to say that a file is being "transferred" instead of "downloaded" in the context of P2P applications.

LimeWire allows you to share or access any file type such as MP3 (music), AVI/MPEG (video), JPG (photo), etc. Because it is written in the cross-platform Java programming language, it will run on Windows, Macintosh, Linux, and other operating systems.
