Limewire is one of the most popular tools among those who want to share or use data from other users. It is a peer-to-peer file sharing (P2P) client developed for the Java Platform, which uses the Gnutella network to locate files as well as share files. Released under the GNU General Public License, LimeWire is free software. Although if you can pay the fee, you get access to the much talked about LimeWire PRO.
Written in the Java programming language, LimeWire is able to run on any computer with Java Virtual Machine installed. Installers are provided for Microsoft Windows, Mac OS X, and Linux. Support for Mac OS 9 and other previous versions was dropped with the release of LimeWire 4.0.10. From version 4.8 onwards, LimeWire works as a UPnP Internet Gateway Device controller in so far that it can automatically set up packet-forwarding rules with UPnP-capable routers.
LimeWire offers the sharing of its library through Digital Audio Access Protocol. As such, when LimeWire is running and configured to allow it, any files shared will be detectable on the local network by DAAP-enabled devices.
