What is an .DUF file?

.DUF is DAZ User File

3D modeling file created by DAZ Studio modeling software; contains character, shaping, pose, and shader materials; similar to the .DSF file but its assets cannot be referenced by any other file; used for sharing between users.

DUF files use the DAZ Scene Object Notation (DSON) format. This format is lightweight, intended for easy transfer of 3D content between applications that implement the DAZ Content Engine. Its JSON syntax makes it easy to parse and human readable.
