|To my understanding you can use UNC path's in a batch file.|
However this shouldn't be very complex to accomplish as you can use mapped drives instead.
I need some clarification.
You want to set a source path (UNC) and target path (Local or UNC?) Then have a new batch file created in what directory (Source or Targert?) and then copy the files/folders from the source to Target?
Let me know as I have something very similar to this that I can modify for you, just need a better understanding of what you're trying to do.
