Blake can you provide me with a quick example of using os.walk.path and
os.path.join using my example?
I'm totally lost at this point. I thought that I understood but I'm back to
droolling with a blank stare. I think I need to sign up for a Python course.

import os, os.path
dirname = "c:\\Documents and Settings\\jj\\Desktop\\"
a = os.listdir(dirname)
for x in a:
    print x, os.path.getsize(dirname + x)
