What is a BPN File?

A BPN file is an automatically saved backup file created by Graphisoft Archicad(CAD), a Building Information Modeling application for designing buildings, interiors, and urban areas. The software has an automatic backup function. Select the backup option in the "Data Integrity and Security" option, and the software will automatically create a backup of the current project (.PLN file).

Archicad saves project data in PLN files, which are the basis for generating BPN project backup files. A BPN file contains a backup of the Archicad project, and both the PLN file and the BPN file are saved in the same folder. Since the BPN file is the latest PNL file actually saved, if the original project file (PNL file) is damaged, just change the backup file BPN to PLN extension for the backup file to use.

When you are working on a project, your system may suddenly crash causing you to lose your work. In this way, Archicad provides an autosave that helps you to automatically save your work, preventing major loss. This is a quick and easy way to recover data in case the main project file is corrupted.

How to Create a BPN File with Archicad?

Select “Options” > “Work Environment”; Click “Data Safety & Integrity” and check the "Make Backup Copy" checkbox. Then, Archicad will create BPN files, following intervals defined by user-set application preferences. If the project (.PLN file) file is corrupted, you can rename the extension from BPN to PLN for the main project file.

Why Can't the BPN Files Be Opened and How to Open?
