F.B.
either she cleans them and files them with supervision, or I do, that's all there is to it. My niece tried this and she thought she wouldn't and then I couldn't hold her down and do it, crazy. I just started collecting prized possession (psp, computer, phone) until she sat willingly or she did it herself with me watching. Worked like a charm. No TV until they do it also works usually within a day or so!
Good luck
