I didn't really understand what you mean by the name of the file, it's suppose to be .rpl if it's a replay, anyways if you can't remember where you installed Toribash try looking in C:/Program Files and if you can't find it there click on Start -> Search and choose "All files and folders" and type in Toribash. Hope that helps
By the way, did you say you saw me on Youtube? If so, do you remember which video?
