lowercaseDir.py not working?

[Philipp Stader]

Hi,

anyone else experiences this problem? I just uploaded some custom maps 
and tried to the run the script.

python lowercaseDir.py /home/bf2/bf2/mods/
Traceback (most recent call last):
  File "lowercaseDir.py", line 62, in ?
    os.path.walk(directory, visit, args)
  File "/usr/lib/python2.4/posixpath.py", line 298, in walk
    walk(name, func, arg)
  File "/usr/lib/python2.4/posixpath.py", line 298, in walk
    walk(name, func, arg)
  File "/usr/lib/python2.4/posixpath.py", line 290, in walk
    func(arg, top, names)
  File "lowercaseDir.py", line 35, in visit
    os.rename(os.path.join(dirname, x), os.path.join(dirname, low))
OSError: [Errno 39] Directory not empty

All help appreciated. I don't feel like renaming everything by hand and 
am not the shell magician i'd love to be.

Kind regards from Germany
