On my PC, I made a new user account for the rest of my family to use (I don't want to use a Guest account). The account type is just Standard. I recently noticed that my brother is lurking through my Application Data folder on my account using the standard user account I made for them.

So my question is: How do I restrict or deny access to my AppData folder so no other user accounts can get in there?

Thank you.
