About BN files
The .BN extension primarily refers to proprietary Bone animation files used in 3D games like RF Online, though it is also used for BLAST Nucleotide alignment reports in bioinformatics.
In the gaming context, .BN files contain the skeletal hierarchy and animation data necessary to rig 3D character meshes. Users typically encounter these when modding RF Online or attempting to extract game assets for use in modern tools like Blender or Autodesk Maya. The main issue is that .BN files are binary, engine-specific, and encrypted, making them impossible to open with standard 3D software without conversion. To modify these assets or use them for 3D printing/rendering, you must convert them to widely supported exchange formats like FBX (for animation preservation) or OBJ (for static geometry).
Alternatively, in scientific research, a .BN file may be an output from the NCBI BLAST tool, containing nucleotide alignment data. These are often plain text or specific report formats that require parsing. For publication or easy reading, these should be converted to PDF or TXT.

The BN Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BN converter.
