BND File

What are BND files and how to open them

Are you having problems opening a BND file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your BND files.

What is a BND file?

BND files have multiple uses, and DB2 Bind is one of them. Read more about the other uses further down the page.

DB2 Bind

DB2 Bind files are binary files created by IBM Db2 when an application program that includes embedded SQL statements is precompiled. They store information needed to "bind" those SQL statements into executable packages in a Db2 database. Precompilation with tools like Db2's precompiler or SQL Preprocessor writes the Bind file if the BINDFILE option is used. The BIND command reads the Bind file, checks syntax and access rights, then creates or replaces a package in the database that the application program uses at run-time.

Bind files are produced by the Db2 precompiler when the build options specify deferred binding (BINDFILE) rather than embedding the bind step into compilation or package creation. Once a bind file exists, administrators or developers use the BIND command (sometimes via APIs) to process it against one or more target databases, creating package objects that Db2 uses to drive SQL execution and access management.

Each Bind file can be identified by certain internal signatures. The first 8 bytes at offset 0 are ASCII "BINDV02" (hex 42 49 4E 44 56 30 32), and there is a byte 0x30 at offset 37. These signatures help tools automatically recognize files conforming to this specific Db2 Bind format.

How to open BND files

Important: Different programs may use files with the BND file extension for different purposes, so unless you are sure which format your BND file is, you may need to try a few different programs.

While we have not verified the app ourselves yet, our users have suggested a single BND opener which you will find listed below.

All known file formats using extension .BND

While DB2 Bind is a popular type of BND-file, we know of 2 different uses of the .BND file extension. Different software may use files with the same extension for different types of data.

Tales Of Eternia Online Game Data Archive

Tales Of Eternia Online Game Data Archive files are asset containers used by the PC client of Tales of Eternia Online, an MMO released in Japan in 2006 which ceased operations in 2007. They bundle together game data such as textures, icons, battle actions, character/asset registries, maps, and other resources shipped with the client.

These archives are produced by Namco's original game client, which writes multiple custom container families. Files are read by the same engine (or by preservation/reverse-engineering tools) when loading resources at runtime. Common container families include texture bundles for graphics screens, icon registries, database-like tables for combat actions, catalogs of assets keyed by symbolic IDs, and manifest files to support content integrity.

The format is structured in several named types: BNKD (textures, compressed with Namco LzComp2, color formats like A1R5G5B5 or palette8), IDTB (symbolic-ID dictionaries encrypted with Blowfish using "idtable text"), ICND (icons), TDAB (battle-action databases serialized using a typed-stream library "Sys_CChunkFile.cpp"), CRSD (character/asset registry, per-record Blowfish with key "crs text"), NNTB (resource-alias maps), and ATDT/PKDF/CPDT (content-hash manifest family).

Internally some table data are encrypted record-wise using Namco's Blowfish implementation; others are compressed; many employ a chunked stream layout matching Sys_CChunkFile, which structures data in typed records and arrays, often with offset tables and pointers to string names, entries and nested parts.

Various apps that use files with this extension

These apps are known to open certain types of BND files. Remember, different programs may use BND files for different purposes, so you may need to try out a few of them to be able to open your specific file.
