I've got a couple of 120G disk that contain files in a serries of
directories. I need to split these up to allow my DLT40 tape to back up
smaller checks.

What I have in mind is something like this:

/foo/bar/[A-J]*
/foo/bar/[K-z]*

But if I put that in the disklist file amcheck says it's invalid. 

Is there any way I can acomplish this?
