What is an OPJ file

OPJ files mostly belong to OrCAD PCB Designer by Cadence. An OPJ file is a printed circuit board (PCB) design project created with OrCAD PCB Designer. This file contains ASCII text referencing symbols, designs, footprint definition, and project settings. Another type of OPJ file is a project created with Origin data analysis and visualization software. This file usually contains one or more datasets and graphs generated from such dataset(s). The Unicode counterpart of an OPJ file created with Origin has OPJU filename extension. OmniPage optical character recognition software saves a schedule in an OPJ file.

How to open OPJ files
