Description
Privileged Locations allow the user to selectively trust files, folders, and hosts to bypass some security restrictions, such as enhanced security and protected view. By default, the user can create privileged locations through the GUI. Disabling Trusted Files and Folders disables and locks the end user's ability to add folders and files as a privileged location prevents them from assigning trust and thereby exempting that location from enhanced security restrictions.
