Taking Jeremy's code and attempting to print the contents of a 
directory, I see that it fails on my Win2K system when given a path 
like "c:\\dir1\\dir2\\dir3" (regardless of how I specify the path). 

When I print the contents of root, dir and files before entering 
the lower-level loops, I see that *dir* contains an empty list when 
root contains "c:\\dir1\\dir2\\dir3". That is, the contents of the 
lowest-level directory won't be printed out because dir has no list 
elements, although *files* does. So it looks like you'd have to 
check for the empty dir and handle that situation separately.
