I tryed with that but I can`t rename it. The movie is converted from avi to divx with a divx program and stupid me to leave the movies in the "document an settings" because the computer broke down and when I got it back all was erased. I have tryed search on the net for a program to convert back from divx to avi but havent found one yet. There are many programs that promises to convert divx to avi but none of those could do the trick.
go to folder options view and click where it says hid file extensions then change avi to divx no converting needed and should work seeing as they are practically the same files. * but only do this to avi - divx any other movie format will not work
