I don't know if this is easy or hard but a scan function I would like would be for folders like Cabinets and Titles (etc). A scan that just removes unneeded files, files that Mame does not recognise or can use. I don't want a list of what is missing, I would like to search for those myself. However a scan that removes "Title" files that are not used by Mame would keep my files trim & tidy.
