Mmm, no idea. But apprently the code that is failing is:
parentname = os.path.dirname(filename)
if not os.access(parentname, os.W_OK):
raise IOError("directory ``%s`` exists but it can not be written"
% (parentname,))
Can yoy run this in your Windows machine and tell me whether os.access is
reporting that you have writing permission in "../../Bureau"? Can you
experiment passing an absolute path or with backslashes?
Cheers,
