Remarks

The scenario for using SystemProperties is when you are defining search indexes or other operations where you want the indexing to use the same name for a property that the system has already defined, as one of the Windows file properties.

Some of the SystemProperties properties return a string name directly. For example, SystemProperties.Title returns the string "System.Title". Some of the SystemProperties properties return a helper object. For example, SystemProperties.Video returns a SystemVideoProperties object. You can then use this object's properties to get the name for a video-specific Windows file property, for example SystemVideoProperties.FrameHeight returns "System.Video.FrameHeight".
