Yes, that's a good case.
But, you've already got some object/data structure that describes the 
file, right?
[ A path, or something ]

Attach _that_ to the exception, and Bob's your uncle.

Personally, I think that the ".what ()" field in the exception is an 
anachronism.
No one is going to show that string to end users.
