Premiere Pro Legacy Title Files - Where are they stored?

Hi - and thanks in advance for any help or insight you might offer!

I am backing up what is for me a large project. Of primary importance are the legacy (I know, slow to adopt here) titles that are in Cyrillic alphabet which I cannot read. I really need to keep them in case they come back for changes at some point. I have them in a bin in the project folder, all 200+ of them nicely named and kept in folders for the different videos they go to. But I cannot find them anywhere in my backup.

Going back several years and versions of PPro, I find this tidbit:is this still the case, are the titles in the PrProj file?

As of about Premiere 5 (before Premiere Pro days), the program stopped using TitleDeko, and the Titles are now stored within the Project file (PRPROJ) in XML code.

Is this still the case, are the titles in the PrProj file?

Thanks again for any help!
