finding renamed files

[Mark Powell]

Hello David:

Assuming you are dealing with jpegs only, you could use exif data in
your comparison algorithm.  For example, if you know the source of all
images you can parse the exif data to see if an unknown 'image software
source' field exists.  If yes, then it is deemed to have changed.

Alex Tweedly has a stack "libEXIF" that does this well.  I think it is
in RevOnline.

Thanks to all who made suggestions re the above.  The detailed files
looked promising, but ultimately a bit disappointing.  Maybe last
accessed might offer something, unless of course the file is renamed
without opening.  Mind you, I am only interested in files renamed
because they *mean* something to the user, so I may well want to ignore
anything renamed without opening.  I will call that a 'feature'  ;-))

I will experiment and see what works best.

Best Wishes,
