Sorry if this is a really dumb question, but I can't quite figure it out.
If I make a document library with no permissions for other people but me, will I and only I be able to see what's inside?
And if I add a document named X to that document library, and I share that document with person A, will person A then have access to document X (without seeing other documents like document Y and Z)? Or will person A have no access to the document at all because the document library in which document X is in has permissions set for me only?
I'm just confused about this.
