I see. I misunderstood your question. Testing for "there is a stack" is 
a good approach, as suggested. If that takes up too much memory, you 
could also open the file as a text file, read for 30 or 50 characters, 
and see if the word "Metacard" is in there. The second line of every Rev 
and MC stack includes that string. Of course, this may change in the future.
