My Google Drive (company provided: email@example.com) is getting pretty full, and I've been going through it and deleting files. I came across a rather inappropriate Doc someone sent to me. It was sent through a link, which made me wonder what kinds of files my admins can monitor. So this file was not directly sent to me. Instead, I received it through a link. I've since deleted it, but can my admins still find it, and if so, why? note that it was a view-only Doc. Also, can they monitor my Drive without my knowledge?
(please no "5 laws of security" or "if you can't trust your admin" answers. I want an actual answer.)
