Once again, this is a terrible idea. It's where Microsoft got it wrong 
with the hidden Thumbs.db.  Extremely awkward when copying directories 
around. There should never be any extra baggage around my files.

It is already hugely annoying that "deleting" a file on my camera in 
Nautilus moves it to some hidden Trash directory on the memory card.
