How can I iterate all files and subdirs in a Dir,

Try os.walk. More specifically, try:

top="."
import os
for root, dirs, files in os.walk(top):
    for name in files:
        # do something with each file as 'name' (a)
        pass
    for name in dirs:
        # do something with each subdir as 'name' (b)
        pass
    # do something with root (dir path so far)
    # break at any point if necessary

To answer the question in your comment, at point (b) in the code, you can handle any subdirectory logic (also you can check to test that you have the right subdirectory to do certain custom logic on), via another function or directly/inline.
