What is a BPN file?
A .BPN file is an Archicad Project Backup File created by Archicad, a popular architectural design tool developed by GRAPHISOFT. When a user saves a project, the software automatically saves the previous version of the file with the .BPN extension. This allows users to recover their work if the main project file becomes corrupt, is accidentally deleted, or if a recent change needs to be undone.
How to open BPN files?
You can open .BPN files directly using Archicad on Windows or macOS. You can also rename the file extension from .BPN to .PLN (the standard Archicad project format) to open the file normally. This makes it easy to restore a previous project state.
