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 File → Open..., select the ".opj" file type, navigate to the OPJ file location, and click Open.
