I've just used Recuva to try and locate/recover some 'lost' photos. Without using the deep scan, I received:- [A:] 29,266 files found, 404,258 ignored. The majority of files were described as 'No preview available', however, apart from a number of recognised photos of mine, there were thousands of totally unknown photos, weird images, magazine pages, road maps, coloured boxes/patterns, etc., etc. Can you please explain how all these unknown/unseen by me files/images have been found in my computer hard drive? I should add that I have not actually selected any files to be recovered as the 'lost' photos have not been shown, presumably 'No preview available'?
