What is a PBU file

PBU files mostly belong to PBU Editor. PBU files are used as backup archives for industrial devices. In many cases, these files store the Printer Backup Unit data created by the PBU Editor.
When a device like a Proface HMI needs restoration or recovery, the PBU file acts as a container for the saved configuration and system settings.
Key points summarized by FilExt.com include:

Backup storage – It holds configuration details for system recovery.

Device restoration – Used to restore the settings during maintenance.

Proprietary format – The file format is specific and requires the correct software, such as the PBU Editor, to access.

FilExt.com tip: If you need to open and view this file, use the official PBU Editor provided for Proface HMI backup files. This ensures the data is handled properly and remains uncompromised.
