Thank you, but it didn't help. InfranView came up with a error that is saying "Unknown file format, empty file or file not find". Does that mean that my photos is lost.
If so, I don't understand it, because it's a JPEG file and the size is the same as before I lost them, so there must be some content.
Again, thanks for you help
EDIT: I just recovered one of the "no preview available" photos, and I recovered it before installing InfranView and then I changed the program who opens it.
