Where does opus store advanced rename information?

I had quite a collection of advanced rename scripts, then I rebuilt my computer.

I have my old system drive on my machine in a readable state but I am unsure where I would look to extract the old rename settings.

Sadly I forgot to export them to orp files prior to the rebuild.

is there somewhere on the disk I can look for them?
