In order to iterate over all assets in a scene the method Interface::EnumAuxFiles() should be used. To iterate over assets used by a particular animatable item in the scene use Animatable::EnumAuxFiles()).

Note: In portions of the SDK the term "auxiliary file" which is a hold over from earlier versions of 3ds Max is still used. The term "auxiliary file" is synonymous with asset file.

If a plug-in uses any asset files then it should override Animatable::EnumAuxFiles() to allow the 3ds Max SDK and other plug-ins to access them.
