from os import walk
from os.path import join
path = 'C:\\'
# Creates list of the items in directories (+subdirectories)
items = [join(root, file) for root, subdirs, files in walk(path) for file in files]

In MS Windows it works like this:	1 - Hold the "Shift" key, right-click the folder containing the files and select "Open Command Window Here."	2 - Type "dir /b > filenames.txt" (without quotation marks) in the Command Window. ...	3 - Inside the folder there should now be a file filenames.txt containing names of all the files etc.
