What is a BG file?

BG files mostly belong to Wecon HMI Designer. BG files serve as a container for different types of data.
This extension is most notably used for HMI images in industrial settings, where the file is stored as XML by software like Wecon HMI Designer (more details).
Other observed uses include:

An encrypted JPEG image often seen in ransomware cases.

A bitmap graphic used as a resource or asset in games.

A binary backup or data file generated by the Godot Engine (Godot Engine).

A corrupted GIF image acting as an Aseprite backup.

An MHTML file saving a single webpage (linked with Blink).

An encrypted log or background image file as used by Adobe Photoshop.

A compressed PNG image archive packaged with ZIP.

FilExt.com tip: Because the same BG extension can hold such varied content, determining its origin is key. Knowing the source helps in selecting the right application to view or edit the file.

How to open BG files

Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your BG file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BG file directly in the browser:.

BG format details:

The file format determines how the data is stored in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the BG files:

The BG file type includes different formats for different programs. The two most common formats are as follows:

• 30% of all BG files are based on the popular 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 contain text and words, not binary data. A typical file size is 580 bytes. The file type is old but is used even today. The keywords <?xml version="1.0" encoding="utf-8"?>, discription, state id, type, draw name, image, width="100" height="100", vg name, vg ver and color="0xffffff" transparent="no"><state are typical for these files. The file name arrow1-00.bg or button1-00.bg is typical for these files. Files like these are about lamp, motor, meter and logo.
• 10% of all BG files use the same file format, which have the signature 00 00 00 02. If you open these files in a text editor, you will see only illegible characters. The files are 150 KB to 500 KB in size, with a median of 430 KB. Certain words are almost always found in the files, such as FExif, JFIF, by.blooddy.crypto.image.JPEGEncoder, (((((((((((((((, , #&')*) and -0-(0%()(. A usual file name is 142376.bg.

All other BG files (60%) have no uniform format, often e.g. PrintFox/Pagefox bitmap, JPG, PNG, ZIP and mode. They are often associated with debug, kiss, corrupted or base. Drag & drop your file here to see the file format and a preview of your BG file!
