You can use P2P Share Spy to search the internet/world for computers with shared files!
Browsing and downloading is done with Windows Explorer, which can handle any file type: MP3 , MPG, AVI, DIVX, JPG, Etc!
Other file sharing programs only allow you to download files that have been shared specifically for that program, but P2P Share Spy lets you browse and download publicly shared files no matter what program they were shared with!
Unlike Kazaa and Morpheus, P2P Share Spy only finds shared files, it does not share your files with anyone else, so you won't have to worry about RIAA knocking on your door with a lawsuit.
