A DN file contains a 3D scene created by Adobe Dimension, a professional program used to create real-life mockups and abstract artwork. It stores information about objects and graphics placed on a canvas, along with settings applied to the scene, such as lighting intensity and camera perspective. DN files are commonly created and shared among graphics professionals designing life-like visualizations of products.
