This is interesting, but once I downloaded Vampire Diaries episode from torrent and all I could get was these r0 files. I didn't know at that point what to do with and the uploader must be joking by uploading these junk files.
But few days back when I needed to install 3ds max on windows 7 machine. I downloaded it from torrent and I got r0 files. Then I searched it on net and found following solution, it is fairly simple !
