Something that's curious to me. After you upload 999,99 GB, you'll have 1TB, right?
Will the UL meter at the top then continue in TB measures? Like, 1 TB, 1.1 TB and so on.
if so, how will you be able to see exactly how much you've uploaded?
Sorry it that's being too noisy, I'd just like to know

I'm currently at 17.90 TB

So, your assumption is correct.

That is correct. You can see what you actually uploaded in your main profile. However, I suggest that you do not upload files that large at one time. You have to be mindful that not everyone has a good bandwidth, or ratio for that matter. Even if we all had phenomenal bandwidth, we human beings on this planet cannot go through millions of files in one day.
