The Padding Object is a dummy object that is used to pad the size of the Header Object. This object enables the size of any object stored in the Header Object to grow or shrink without having to rewrite the entire Data Object and Index Object sections of the ASF file.

For instance, if entries in the Content Description Object or Extended Content Description Object need to be removed or shortened, the size of the Padding Object can be increased to compensate for the reduction in size of the Content Description Object. The ASF file can then be updated by overwriting the previous Header Object with the edited Header Object of identical size, without having to move or rewrite the data contained in the Data Object.
