It is a program that uses a peer to peer sharing network but I have found it to be really bad. You can get music, programs, pictures, videos, etc. but like I said it is not worth the trouble it brings. Everyone I talked to that uses it has got at least 1 virus. I've even tried it and 9 out of 10 times my anti-virus detected that the file is corrupted. So I would not use it. It's not worth the trouble. Hope this was helpful
