LimeWire is a peer-to-peer (P2P) file-sharing program used to share and distribute content on the Web. LimeWire enables users to access or share any file type, such as AVI/MPEG (video), MP3 (music), JPG (images), etc.
LimeWire Basic is free to use, while LimeWire Pro is a paid version that promises faster peer-to-peer and downloading speeds. LimeWire runs on Windows, MAC OS X, Linux and other operating systems supported by the Java software platform. LimeWire uses the Gnutella network and BitTorrent protocol.
LimeWire allows individual users on the Internet to make music, videos and other files available for direct access by other users. It also allows users to search for desired content on other users' computers and download those files.
Limeware does not use any centralized server to store files; instead, it directly transfers files from one user's (peer) hard disk to that of another user. This is the reason why the term "peer-to-peer" is applicable to Limeware sharing.
LimeWire is written in Java programming language, and runs on any computer with a Java virtual machine installed. LimeWire version 4.8 or later works as universal plug and play (UPnP) Internet gateway device controller, which automatically sets up packet-forwarding rules with UPnP-capable routers. Users share a library through Digital Audio Access Protocol.
