I also with this problems.
I have made a test script.
There is a problem with os.chdir(): It doesn't work with \\?\ notation.
And there is also a problem, if you use
```
import os
import pathlib
import tempfile
with tempfile.TemporaryDirectory(prefix="path_test_") as path:
new_path = pathlib.Path(path, "A"*255, "B"*255)
extended_path = "\\\\?\\%s" % new_path
os.makedirs(extended_path)
print(len(extended_path), extended_path)
```
os.makedirs() will work, but the cleanup will failed.
Output is:
```
567
\\?\C:\Users\jens\AppData\Local\Temp\path_test_8fe6utdz\AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
