I'd like to think this is what every reasonable adult meant when they said files — an enumeration of the tapes, but unsurprisingly the psychos are playing semantic games because they are allowed to get away with it. I suppose you're right, at this point it's better to just explicitly demand the tapes, but unless there is something more than just demanding they will dismiss you all the same. Yes, using the braindead "what, you want to see child porn?" rhetoric.
