Error Trying to fsync a Directory

I'm trying to fsync a directory, to ensure that rename operation occurs. The problem that I'm having is that Python keeps returning a permission error, even though I have full permissions for the various folders I've tried this on. directory = r'C:RandomPath' os.access(directory, os.W_OK) os.access(directory, os.X_OK) os.access(directory, os.R_OK) True, True, True fd = open(directory) os.fsync(fd) IOError: [Errno 13] Permission denied: 'C:\Random\Path' Am I doing something wrong, or is there something deeper going on?
