Yes, I like slick too but sometimes when it's something you're only doing once 
or twice for testing purposes and don't need it on an ongoing basis then brute 
force methods are adequate.

Yes, that's exactly what I'm looking for: a way to determine which 
directories did in fact span tapes, NOT which ones will span tapes. So, 
this is an "after the fact" question. I can certainly do as you 
mentioned but was looking for a slick way to determine this without 
trial and error?

Some of the save sets have a small number of top level sub-directories 
so it won't take too long to find one that spans, but most of the save 
sets have a lot of top level sub-directories, so that will take much 
longer. Obviously, at least one of them must span two tapes.
