I'm confused. You said you only were concerned about the _current_
directory's subdirectories not having sub-directories, right? IOW You
have:

ROOT
 FolderA
  -FolderA1
  -FolderA2
   /FolderA2A
 FolderB
 FolderC

And in ROOT, you only want to see :
FolderB
FolderC

And in FolderA:
FolderA1

Right? If so, whether or not FolderA1 has subfolders is irrelevent in
root. The code ethan posted will provide you with that. I have very
similiar code for one of my nav-systems, opnly it is the opposite, I
show folders (and various other objects) and their subfolders (and
various other objects) only.

Maybe I read it wrong, but I thought you said you wanted only folders
with subfolders _in the current directory_.

Maybe you need to rephrase your question?
