If there are three or more files for comparison, the one moved is not necessarily the most recent in time. Can it be done to only move the most recent one? Maybe I need to trouble you to improve it. thanks!

It's too troublesome. I've lost interest in thinking about this question. Remember to state the requirements clearly at one time when asking questions in the future.
