Had to reimaged my HD. Have all my files saved from the directory with custom songs and songs.dta

However I am having trouble restoring a bunch of other DLC I originally had downloaded on the console. I believe those files may have been stored elsewhere, as they were not restored. Or perhaps I need to reactivate the files.

I still have the original PS3 with all the purchased content as well.

What’s my best method to restoring the other files that are missing?
