Do you have to use Windows Batch?  Some basic PowerShell would be far easier.

This does it.
Make a .bat file of this.

- Change the variable values of FolderA, FolderB, and FNLog to your needs.
- This .bat is in test mode. To run it for real, remove the ECHO on line 18.
- In addition, a log of results is sent to file FNLog.

@echo off
setlocal enabledelayedexpansion
