Folders contain file objects. File objects contain data acquired by the device such as images and sounds. This method enables applications to identify the type of any item in a hierarchical tree of item objects in a device.
An item may have more than one type. For example, an item that represents an audio file will have the type attributes WiaItemTypeAudio | WiaItemTypeFile.
