Tuning files??

I wanted to ask about the tuning files created inside of the "Sims 4 Studio" main folder inside of "My Documents".  Since I do not know the purpose of these files, I was wondering if they should be left alone, deleted, etc.  All the files were created about 1 month ago one the same day, about the same time.

Today I ran a bunch of batch fixes on my CC.  So I was concerned about incompatibility and inconsistency with any fixes to my game files. 

Thank You in advance
