The operating system and every application out there treats a "move" as simple a copy then a delete (new file at the source, delete at the destination).

You would need to monitor both sides and have a CRC or hash of the file before the operation begins (very slow) so you could verify it's exactly the same file contents since properties of the file/folder would have changed.

"Moving" is simply human understandable terminology for a copy/delete and the operating system performs two steps behind the scenes. It would not be viable for the software to keep a database of file contents to match both size and determine a "move" took place so this will never become a feature.
