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.

To save an OPJ file in Origin, select File → Save project or Save Project As..., name the file, choose the save location, and click Save.

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.
