What is an .BDF file?

.BDF is Binary Data File

File Type 2 BSDiff Patch File
Category: Game Files

Patch format used to update video game ROMs; may also be used to produce patches for binary files.

Patching is commonly done to video game ROMs for one of two reasons. One reason is that the user wants to play a game in English that wasn't originally created for English users. The other reason is that the user wants to alter gameplay, such as the level order or character dialogue.

The bsdiff/bspatch tools can be used to create and apply BDF patch files:

  • To create a BDF patch file that makes your desired goodfile.123 from your original badfile.123, type bsdiff badfile.123 goodfile.123 patch.bdf.
  • To apply a BDF patch file to your badfile.123, which subsequently creates your goodfile.123, type bspatch badfile.123 goodfile.123 patch.bdf.

NOTE: The .BSDIFF file extension may also be used instead of the BDF extension but it is less common.

File Type 4 Bulk Data Input File
Developer by: MSC Software Category: Data Files Format: Text

Input file used by MSC Nastran, a program that analyzes structures such as aircraft, buildings, and spacecraft; contains bulk data definitions to be input into MSC Nastran to analyze the stress and strain levels of model structures; includes information such as the name of the bulk data, the number of grids, and the node locations of the elements that make up the models; data appears in the FORTRAN programming language, which was originally developed by IBM, and stands for Formula Translating System.

BDF files are separated into 5 sections:

  • Nastran Statement
  • File Management
  • Executive Control
  • Case Control
  • Bulk Data
  • NOTE: The BDF file is similar to the .NAS and .DAT files, which are used to input data by MSC Nastran.
