Similar to that of an operating system, in which a root directory contains both subdirectories and files, a subfolder is used to hold foldered objects. Subfolders reside in cabinets or other subfolders.

The Display Folder Domains preference that is located under the Security category determines the visibility of the domain to which a subfolder belongs. The domain can appear when creating and editing folders. If the preference value is Yes, the subfolder’s domain is displayed. Inheritance of the domain from a parent cabinet or subfolder is also displayed when creating or editing a folder. If the value is No, the domain information is not displayed.
