It's always best practice to lock your folder from being open by other users when using your computer. Below is the windows security to grant certain user to access the folder.

1. Right click the folder for properties\security\advanced tab
2. Then open Permission, Auditing, Owner tabs, from there, add the allowed user and remove those users who are not allowed.
3,After done so, go back to folder properties\security\edit...From therem, edit the user list once again..
