2.25.2 PropertyBag

The PropertyBag property set format, identified by FMTID_PropertyBag ({20001801-5DE6-11D1-8E38-00C04FB9386D}), is used in applications that persist an object as a property set, typically by saving state variables as properties. A PropertyBag property set's associated CLSID SHOULD identify the application or component whose object is persisted in the property set. The properties contained in a PropertyBag property set are application-specific.
