You are under a wrong assumption. You think os.listdir() returns a list
of absolute path elements. In fact it returns just a list of names. You
have to os.path.join(dir, file) to get an absolute path.

Anyway stop reinventing the wheel and use os.walk() as I already
explained. You can easily spot the depth with "directory.count(os.sep)".
 os.path.normpath() helps you to sanitize the path before counting the
number of os.sep.
