The question is in good faith. 15m files is ALOT of files and one wonders how an individual accumulates so many and that they are also important enough to have backed up on dropbox no less. Is it a bunch of very small files with many versions? I mean you obviously don’t have to answer, but it just seems silly to attack others asking legitimate follow up questions. It is now obvious that you value your privacy to a higher level of secrecy than the poster thought.
