It should work. In fact, I wrote a stack to do that (for music files) 
last year and it worked OK for them. Only weakness was that it was slow 
- I considered adding an "index file" to each directory, which would 
store the file names and md5 signatures, but hadn't got as far as doing 
that.

Other weakness -I decided it wasn't worth adding refinements because it 
was a one-off effort to merge two lots of music files and I got it 
completed OK before I had refined the stack, so I didn't keep the stack :-(

I'll try re-creating it from memory and see if it's as easy as I 
remember ...
