file id/hash

[Mike Kerner]

I thought I read something about being able to grab and search on the
hash/id of a file.  That would certainly be useful for those times where
you move a file somewhere and then forget where you put it, and you can't
remember the name.

On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
