What is a BPN file?
A BPN file is an autosaved backup file created by GRAPHISOFT Archicad, a BIM (Building Information Modeling) program used to design and construct buildings. It saves a backup copy of the current project (.PLN file) automatically created by the software if the backup option is set in the application's "Data Safety & Integrity" preferences.
