[* Typo correction in the second file=> depth *]

 What I'm still undecided on is the appropriate depth for a file!  For example:

root_file => depth == 0
root_dir => depth == 0
  file => depth == 1 or 0 ? (I'm using 1 for now)
  dir => depth == 1
    file => depth == 2 or 1 ? (I'm using 2 for now)
