Yep, I can see two folders in there and your 26.76MB PDF file. Also lets me delve into the subfolders.

I always wondered about this as well. Surely if you share the URL with someone, they could reshare it and as you say you then don't know who has access.

Yes that's my point.

It seems to undermine the idea of security. I'd rather have that functionality limited in someway that makes it clear that you are making the folder "public" and no longer private.

Public means that anyone can access it without any verification/authentication info. Private in this context would mean that it's limited to people who received the link.

Yep - but I challenge you to determine that from the sharing dialogue.
