What is a .BPN file?

A .BPN file is a type of backup file specifically used by GRAPHISOFT Archicad, which is a software program designed for Building Information Modeling (BIM). This software helps architects and designers to create detailed 3D models and technical drawings of buildings. The .BPN file contains a backup of an Archicad project file, which has the extension .PLN.

When you are working on a building design in Archicad, the program can automatically save a backup copy of your work. This happens if you have enabled the backup feature in the program's settings. To turn on this feature, you go to the menu, select Options, then Work Environment, and finally Data Safety & Integrity. Here, you need to check the box that says "Make Backup Copy." Once this is set up, Archicad will save these backup files periodically, ensuring that you have a recent version of your work saved in case something goes wrong, like if your computer crashes.

The backup files are saved in the same folder as your main project file (.PLN) and are named with the .BPN extension. If you ever need to use one of these backup files because your main project file gets corrupted or lost, you can simply change the file extension from .BPN to .PLN and open it in Archicad as your primary project file.

To open a .BPN file, you will need to use GRAPHISOFT Archicad, as it is the program that creates and uses this type of file. Archicad is well-regarded in the architecture and construction industry for its ability to help users visualize and manage large building projects effectively.
