DeskProto is 3D CAM software from Delft Spline Systems. It uses .dpj files for projects in which 3D models are prepared for CNC machining.
A .dpj file contains the saved DeskProto project, including the work in progress and the settings needed to continue working on it. It is a native project file rather than a general-purpose CAD exchange format.
DeskProto is available for Microsoft Windows, and the .dpj format is intended for use with that software.
Open the .dpj file in DeskProto on Microsoft Windows. Use DeskProto's Open command and select the file.
As far as we know, DeskProto is the program used to open and edit this native project format.
Open the project in DeskProto to export it to a finished CAD/CAM file or exchange format.
DeskProto can also use the project to generate and export CNC toolpath or NC output for machining. That output is not a converted DeskProto project and may depend on the selected machine and controller settings.

The dpj file extension identifies a project used by Borland Delphi. Delphi is Borland's development environment for creating Windows applications with the Delphi programming language.
A DPJ file stores information that defines the project and helps Delphi work with its source code and other project files. It is therefore classified as a source code and script file rather than as a finished application.
The format is primarily associated with projects created with Borland Delphi.
Open the dpj file in Delphi on Microsoft Windows. Use the program's project-opening command and keep the project's related source files available in their expected locations.
Compatibility can depend on the Delphi version that created the project.
A DPJ project file is not normally converted to another file format. Open it in a compatible version of Delphi and save or migrate the project using that development environment if a different Delphi project format is required.
