Copy Makernotes to EXIF?

[dipmach]

Hey guys,
I'm new to this metadata stuff, so this may be a question with an obvious answer, but please bear with me.
I have over 10000 photos from 2000 onwards that have Makernotes data like in the attached screenshot. Is there a way to copy this data to EXIF?
I want to use another tool to take the EXIF data and make a neat folder tree out of it, while preserving the data in the Makernotes. Thanks!

I kinda figured out what I wanted to do, and got it working on one file:
exiftool -tagsfromfile ts.jpg "-filemodifydate<datetimeoriginal" ts.jpg

I don't need to mess with the other metadata, just need the datetime made available to Windows essentially. How would I make this work recursively with directories and multiple files?

To make your command work recursively, do this:

exiftool "-filemodifydate<datetimeoriginal" -r DIR
