I'm not asking for private data, I'm just trying to understand the use case...

You are arguing in bad faith. It seriously does not have to concern you (unless you are my host which has implied bandwith restrictions before I signed a contract).

I'm not arguing with you at all when I asked the question. I'm just curious about outlying use cases. Is being curious bad?

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.

If that is the case, these vague and hypervigilant security posturing type replies run counter to their interest.

By default, I assume the absolute worst when it's likely something innocuous.

Wouldn't the best approach be to simply say "yeah just tons of logs and cat pics" or not to reply at all?

You could have just said Linux ISOs like the rest of us.
