What is a BF file?

BF files mostly belong to Prince of Persia by Ubisoft. A BF file contains data (sound effects, textures, graphics, and controller settings) used by various video games. Despite having the same filename extension, BF files used by various games are not saved in the same format. For instance, the BF file in Prince of Persia and other Ubisoft games is a data archive saved in BigFile format. Microids video games such as Nostradamus: The Last Prophecy use a different BF format. Another type of BF file is a script written in Befunge or JSFuck programming language. BF is also the filename extension of a font project created with Birdfont editor.

How to open BF files

You need a suitable software like Prince of Persia to open a BF file. 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 BF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BF file directly in the browser:. Just drag the file onto this browser window and drop it.

BF file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the BF files produces the following result:

The BF file type covers different formats for different programs. The following file formats are most commonly found in BF files:

20% of all BF files use the same file format, which have the signature 00 00 00 00. These are binary files, so they do not contain words or text. A typical file size is 9 KB. This file type is based on cutting-edge technology. The keywords FLW0 are typical for these files. Examples of file names are e010_001a.bf. Files like these have the following tags: fscr, script, tutorial and chat.
15% of all BF files use the same file format, which can be identified by the letters "BIG" at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The file size is in the range of 410 MB to 2 GB. Examples of file names are PRINCE.BF or pop3.bf. These files are attributed to clean.

All other BF files (65%) have different formats, such as Cryo Interactive gamedata, TIFF, ABE, BRITONLEAPDIG, gamepads and BUG. The category is aspirine, taranael, common or sound. Just click the "Choose your .bf file to analyze" button on this page to find out what your BF file is.
