Bryce tree file
File type: 3d graphics, CAD-CAM-CAE file
A bto file is a tree model used by the Bryce 3D landscape and scene-generation application. It stores the 3D data for a tree used in a Bryce scene.
The file belongs to Bryce rather than being a general-purpose 3D model format.

Bryce, associated with DAZ 3D, is a 3D graphics application for creating landscapes, scenes, and rendered images. A bto file contains a Bryce tree model that can be used as vegetation in those scenes.
Bryce tree files are component files for the Bryce environment, not complete Bryce scenes. They were used by Bryce on Microsoft Windows and by Bryce for Mac on Apple macOS and Mac OS X.
The bto format is obsolete and is no longer a current interchange format.
Open a bto file with Bryce on Microsoft Windows or with Bryce for Mac on Apple macOS or Mac OS X.
Because the format is obsolete, current 3D applications may not open it directly.
If Bryce can open the file, use Bryce's available scene or export functions to transfer the tree into a supported output format.
