Ok so I rebuilt my computer and backed up my old drive. Some how though some files got deleted and I found them in the hidden RECYCLER folder on my old computers backup. I thought no problem I will just move them over to the new system. Moved them with no errors however none of the files will open. The mp3's tell me " Th file you are attempting to play has an extension (.mp3) that does not match the file format." and none of the exe will install and the txt are all blank when opened. What is causing this and how can i fix it? Thanks for your time.
