LimeWire is a popular file sharing program that enable users to share or search content over the Internet through P2P and Bittorrent protocols. This technology allows fast speed for transfers (downloads and uploads) because there are many connected users to Internet and they share different files; when an user download a file, that file is gathered from all other users in the same time and this reduce significantly the time spent to save a file.
Since 2010 when this service has been shut down, users can use different replacements or LimeWire alternatives such as uTorrent, Frostwire, eMule, Vuze and much more.
