.BF File Association 3

A BF file is a source code file written in the Brainf*ck programming language. It contains a program that is meant to be compiled using a Brainf*ck compiler. BF files contain only the characters <, >, +, -, ., ,, [, and ], as well as development comments.

More Information

In 1992, Urban Müller created the Brainf*ck programming language. When creating Brainf*ck, Müller's goal was to create a language that could be compiled using the smallest-possible compiler. As such, the language includes only eight commands, each of which is implemented using a single character. These characters include:

  • <
  • >
  • +
  • -
  • .
  • ,
  • [
  • ]

While the Brainf*ck language is quite impractical, some other developers have latched onto the esoteric language and its structure. When these developers create Brainf*ck programs, they typically save them in BF files. An example Brainf*ck program, saved within a BF file, might look like this:


NOTE: Brainf*ck source code is also saved using the .B extension.

How do I open a BF file?

Because BF files are plain text files, you can open and examine them using any text editor, such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or Github Atom (cross-platform). If you want to run the Brainf*ck program a BF file contains, you can do so using a Brainf*ck development environment or interpreter, such as Brainf*ck Interpreter (Web, Android).
