That deletes the oldFile. What if the move then fails (permissions error, or something)?

Move is just a MOVE, not a MOVE AND REPLACE

On Mac, it's a move and replace (I think).

However, if oldFile is "busy" you may not be able to remove it, rename it or anything else

Yes. That's fine. I just want to replace it if it's not busy.
