Need to create a batch file to select one random file from a folder and copy to another folder

Question

I need to create a batch file for Windows OS that will select a random file from a particular folder, then copy that file to a different folder. I still need a copy of that file to remain in the original location.

FYI, it needs to be a batch file.

Thanks in advance for your help...
