I want to have all the "artwork" outside of RetroFE. By changing the value mentioned, what am I changing? Is it the entire "collections" folder? Or just the "medium_artwork" and "system_artwork" folder? Do I also need to have the info.conf, exclude.conf, include.conf, and settings.conf located in the location selected on baseMediaPath=, or can it remain on RetroFE's collection folder?
