I see. Could you please try with [the above PNG](https://user-images.githubusercontent.com/38561704/134718316-798e919e-31ac-474f-a792-d1d81ece26d3.png)?

Ok, I will, but allow me to understand how usage was meant to work. https://github.com/liberapay/git-lfs-fetch.py/blob/23026ff916065ee113cdc898e2670f6d9587a1a5/git_lfs/__init__.py#L163-L169 Why the `os.rename`? Why even a temporary directory in the first place?
