The Filters view of Folder Guard is displayed when you press the Filters button on the View bar or choose Filters from the View menu:
This view shows the filters that you can use to control access to the whole classes of files based on their location and the programs they are being accessed. When this view is active, an additional Filter menu appears on the menu bar of the Folder Guard window. This menu contains commands specific to the filters. When you switch to another view, this menu becomes hidden again.
Note that although the filters are available during the free use period, to continue using them, a professional or another business license must be purchased. If you purchase a home, personal use license, the filters would become disabled.
