What is a BUF file

BUF files mostly belong to Various. BUF files are not a single, standard file type. They serve as data containers or buffers that vary by the application which created them.
  • Accounting & Design Data: Some BUF files use UTF-16 (LE) and store busy accounting records or even embroidery design instructions.
  • Gaming & 3D Modeling: Other instances keep 3D model data—for example, files used for Genshin Impact models or animation blend data. Software like Blender may employ these files, and they can also act as a game model texture buffer.
  • Multimedia Processing: In some cases, they hold a Binary Universal Form. For example, ffmpeg uses BUF files as data containers or buffers (as seen with mov_stco_muxer) to manage video processing. Visit ffmpeg.org for details.
  • Meteorological Data: Other BUF files follow the Binary Universal Form for Representation (BUFR), used to encode complex weather information with tools like BUFRLIB. More info can be found at weather.gov.
  • Generic 3D Model Container: Some files serve as generic data containers for 3D models in applications such as 3ds Max. See Autodesk 3ds Max Overview for reference.
  • FilExt.com tip: This file is a container whose content—text or binary—is defined by the generating software. To open a BUF file, identify its source: for text data a text editor may suffice, but binary versions will need the native application (Blender, ffmpeg, meteorological tools, etc.).

    How to open BUF files

    BUF file format details:

    If you can determine the file format, the associated program can also be determined. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the BUF files is as follows:

    The BUF file extension covers different formats for different programs. But the following two file formats are common:

    All other BUF files (60%) have no uniform format. These files sometimes refer to muxer, stco, data, initial, backup, buffers, meshes, metopb, tokyo or stsz. If you want to find out which format your BUF file belongs to, just click on the button "Choose your .buf file to analyze".
