What are BC files and how to open them

Are you having problems opening a BC file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a BC file?

BC files have multiple uses, and Big Crunch compressed is one of them.

Big Crunch compressed file

These BC files contain data compressed by the Big Crunch compression tool. Big Crunch was an experimental data compression project developed by the four students Eric Chanudet, Jérémie Roquet, Nicolas Ballas, and Paul Baudron, released under the name "the KaBoom group" in the mid-2000s.

LLVM Bitcode Data

These BC files contain program pieces compiled by a compiler based on the LLVM compiler infrastructure into its binary intermediary representation format. LLVM-based compilers can compile several different programming language source code files into program files. During compilation, which is the transformation process from human-readable source code into a machine-executable format, LLVM outputs the compiled instructions in this machine-independent bitcode format. Other tools are used to transform these binary pieces into runnable programs targeted to various platforms.
