deleting an empty Dir, using pathlib.Path

[bowlofred]

A directory in a filesystem may have no relationship between the number of entries inside and the "size" returned by stat. To find if a directory is empty, I would suggest one of:

• get the contents and see if it is empty (os.listdir, os.scandir, Path.iterdir)
  
• just call os.rmdir() on all of the directories, and ignore the errors. If its empty, it will be removed. If it's not empty, it won't.
  

Maybe:

if fel.is_dir():
    if not any(fel.iterdir()):
        fel.rmdir()

Or:

if fel.is_dir():
    try:
        fel.rmdir()
    except OSError:
        pass
