NEF and JPG Synchronized Batch Renaming

mlisowski  wrote Hello, At the time of taking a picture I have the camera set to NEF + JPG.  Over the course of my vacation I deleted some of the NEF files and not necessarily the corresponding jpg.  Using the batch file rename feature in PSE 15 is there a way to keep the nef and corresponding jpg with the same number just different extension, without trying to manually determine, which jpg files need to to be deleted/removed to make sure the number and order match?

I don't see how you could use the batch file rename feature.

What seems possible is to rename and stack the raw and jpeg at import time:
