Thanks for the assistance. I've attempted to use glob, I actually did 
try with os.listdir, but then I had to combine the basename (as I 
understand listdir, is only returns a string with basename) with the 
path, and I have trouble getting that to work with calling it self when 
I ran into a folder, ie the recursivecalls

import os,glob
##use os.walk
def scand(path):
     for current in glob.glob(os.path.join(path,'*')):
         if os.path.isdir(current) == True:
             print "Folder: " + os.path.basename(current)
             scand(current)
         if os.path.isfile(current) == True:
             print "file: " + os.path.basename(current)

scand('c:\\Users\Tommy\\docs')

instead, with an idea of using os.walk whic I havent tried yet, I dont 
much mind limiting it to a windows system as I will be using this on my 
own machine, but I see the idea of not being exposed to OS relevant 
limitations.
The reason for attempting to do this manually is because I am looking at 
making a script that can help me manage my abundent number of articles 
and reports for my research in a sensible way - and I thought it would 
be a good way of learning python.

Ultimately the idea is to expand it into now only listing the folders 
and files, but writing this information to a file (or a database) with 
added info such as notes and comments on the article/report in a .txt 
file that shares the same name as the pdf, and which contains extra info

/Regards
Tommy
