Simple Access File Copy?

What Right include simple access granted?
Can the Client copy my files?
I had a look at the logs all kinds off **bleep** logged but I can't find anything about when the client has logged in and what he have done
(Login at, Logout at, done between, any Files copied?)
I googled for Teamviewer and had look at doku, nothing at all about security, what can the Client do when connected with simple access.

I now found Access Rights in Extended settings and was set to Full Access, changed it to confirm everything.
Does this mean the Client can copy Files without Confirmation?
Where it is logged which files got copied?
