Trying to sort out my photos, which have all kinds of file types and not necessarily any useful camera metadata (like date taken or camera type, etc) that would help me to work out what was a photo without looking at every single thumbnail. Is there any software which can sort through thousands of images and work out what's a photo and what's not?
Windows 7, Linux, or Android... I'm looking for free software, but would consider something very cheap (<5 USD).
