That's ok. Maybe also specify ATOMIC_MOVE to CopyOption ... options in
Files.move() ? Currently the move will be atomic (rename in UNIX
terminology) because the source and target are in the same directory,
but if renaming fails for some reason, it will try the fallback to
copy(src, dst) + remove(src). If you add ATOMIC_MOVE to options, failure
to rename will result in exception. I don't know which one do you prefer?
