Windows - C#- Directory.Move

Question

Is it guaranteed that Directory.Move only renames and not copy/delete as long as it is on the same logical drive?

Answer 1

In fact Directory.Move fails if you attempt to move a directory to a different volume. If you want to perform such a move you have to do the Copy/Delete yourself. I think you can safely assume that Directory.Move will only ever succeed if the operation can be performed without copying files.

Answer 2

Directory.Move is an atomic operation if that's what you're getting at. It doesn't do it as 2 operations. On NTFS at least.
