RchW:
I opened up my file index, similar to how yours is opened, and searched the index for a data file. Although I did not locate a data file in what I think you might call the game directory (the main part of where we've been working with these files, and where my downloads are for caps, jerseys, logos, etc.), I did locate a data file in the Program Files (86) for OOTP. Its file path is: OS(C

\Program Files (86)\Out Of The Park Developments\OOTP Baseball 11\data. Is this significant?
As far as deleting any files, I would never delete consciously delete files unless I created them (case in point is the "_paths" and "paths" files we discussed earlier. I don't know enough about computer stuff to be deleting files I did not create.
I have downloaded quite a bit of Mod stuff from Padresfan site and OOTP itself (All-In-One Mod). Is is possible that a download deleted anything? Another Mod I downloaded for Caps and Jerseys I ended up deleting, because the files were not .png type files.
