What is an .OPJ file?
.OPJ is Origin Project
An OPJ file is a project created by Origin, a data analysis and graphing application used by various scientists and engineers. It contains all of the project contents, which includes data, 2D/3D graphs, and settings.
The OPJ file is the most common file type associated with Origin since it is used as a container for projects. You can open OPJ files with Origin and you can also open OPJ files with Origin Viewer, a free, lightweight program that allows you to view and copy information in OPJ projects.
To open an OPJ file in Origin, select, select the ".opj" file type, navigate to the OPJ file location, and click .
To save an OPJ file in Origin, selector , name the file, choose the save location, and click .
NOTE: The release of Origin 2018 included an updated unicode format for saving projects (.OPJU), which features performance advantages over the older, non-unicode OPJ file format.
File Type 2 OrCAD Project File
CAD project file created by OrCAD, a program used for designing electric circuits, known as PCBs (printed circuit boards); saves references to files included in the project as well as project settings; usually references at least a .DSN design file; used for storing PCB design information together.
OPJ files are saved in a plain text format, but should only be modified using the OrCAD user interface instead of a text editor.
