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.

PBU file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file.

30% of all PBU files save the data in XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are text files, so they contain words and text. The files are on average 13 KB in size and range from 11 KB to 13 KB. This file type is new and state-of-the-art. Several words can almost always be found in the files, e.g.  and device.se. The following filename is common: 4825676ae8c1_EdgeE550_01-06-2020 10-30.pbu or 48256713ca00_EdgeE350_01-06-2020 10-30.pbu. Files like these are sometimes connected to edgee and edfcd.
20% of all PBU files start with the magic bytes PBU, which are always the first bytes of this file format. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. Most of these files are 2 KB to 86 KB in size. The keywords PBU1 are typical for these files.
