If not, have you put a file ending on one of them and then tried it?
Hello!
Recently a few thousand of my photos were deleted from my external hard drive. I have used several free recovery programs (including Recuva) and most of them have allowed me to see the list of files that I want in their various folders. However, when I try to open them the computer won't let me. The message that pops up is: "Windows photo viewer can't open this picture because either photo viewer doesn't support this file format or you don't have the latest updates to photo viewer".
All of the files are .jpg.
I've been going round and round in circles for the past month searching the internet for answers, and I just can't crack it.
Can anyone help me get my photos back?
