Thanks :) I thought the ones in the library were primarily for p4. I would guess you should let P5 create the .png files before removing the .rsr files though. It does it automatically when you load the items for the first time. Getting rid of the "extra" .rsr info saves megabytes of space in the folders. As for the non-library files, I never mess with those :) I've never noticed any in the geometries folders and would probably just leave them alone. Thanks again for the feedback.
