boss's office or partner's office... Because he has seen them. I will grant you that you might have a copy of something at a safe deposit box at a bank but nobody else has access to but generally copies are for multiple people.

I would that a considerable amount that he has shown these documents to people that had no business looking at them. We can speculate as to whether that was simply to feed his ego, for financial gain or commercial gain or something else.
The espionage act applies regardless of whether the documents were classified or not. Whoever could have imagined that we would be talking about applying the espionage act to a president
