When using the id, in upload method you have to delete the old file before moving the new one. Indeed, the name could be the same (same id, same extension), so actually you might be deleting the new uploaded file.

@winzou thanks for the tip I have just updated the PR.

This has been merged in - I think that handling the "delete" is important. As you know, this whole document still needs to be heavily redone, which I've outlined in #2346.

Thanks!
