Just backwards.  The root directory is the ONLY one with a limit.  A
hard drive root directory has a limit like 2048, or something like
that (don't hold me to that number, but the order of magnitude is
right).  Once you are off the root directory, the 'directory listing'
is just another file, and it can be however large a file is allowed to
be. 

The limit is physical disk space.

Correct answers are better.
