Opening a VDB File

The VDB file type is primarily associated with Houdini.

VDB	File extension: VDB
	File type:	data file

What is a VDB file?

VDB files mostly belong to Houdini.

VDB files can serve different roles. The most common use is as an OpenVDB volumetric data format in 3D visual effects. Programs like Houdini use these files to store sparse volumetric grids that represent elements such as smoke, fire, and fluids. This method allows efficient storage and manipulation of large amounts of data without using excessive memory.

Other roles include:

Vehicle diagnostic database: Used by automotive systems from Autocom/Delphi Cars (Visit website).
SQLite database file: In some cases, the file stores relational data in a SQL format (SQLite).
Anti-virus database: Certain VDB files hold data for Dr.Web anti-virus software (Dr.Web).
Design debug data: Employed as a Vivado design binary by hardware development tools (AMD related).
Backup and embedded database: Found in systems using AudaFile and Symisc Vedis, which work with backup and embedded data solutions (Symisc Vedis).
Game data: Minecraft Bedrock uses this format for part of its world data (Learn more).

FilExt.com tip: Each VDB file must be opened with software that matches its internal format and intended use.

How to open VDB files

You need a suitable software like Houdini to open a VDB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your VDB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a VDB file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert VDB files:

Houdini
See the previous paragraphs to learn more about the main application. VDB files are often referred to as Houdini data files because this type of file is primarily created or used by this software.
Dr. Web (Anti-Virus Database) by DialogueScience, Inc.
The identifying characters used for this association are - Hex: 44 72 2E 57 65 62 20, ASCII: Dr.Web.
Norton AntiVirus (Update File) by Symantec Corporation
These files use the following naming convention: The first two characters (VD) stand for Virus Definition. The rest of the file name is a hex representation of a binary structure. The hex will need to be converted into binary to parse the information. You can use Calc.exe for converting hexadecimal numbers to binary and then decimal.

PC-cillin Quarantined File
VistaDB (Database) by Vista Software
VistaDB is an embedded SQL database that lets software developers build small to midsize database applications for .NET and Win32. The identifying characters used for this association are - Hex: 04 00 03 00 00 00 00 00 00 00 04 00 00 00 00 00 00 80 00.

VDB file format details:

If you can determine the file format, the associated program can also be determined. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the VDB files:

The VDB file ending is used by different programs with different formats. But the following two file formats are common:

40% of all VDB files belong to OpenVDB Volumetric Data. They consist of illegible, cryptic characters. A typical file size is 3 MB. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. BDV, string, class, creator, density, HalfFloat, file and Tree_float_5_4_3. Such files sometimes refer to cloud, smoke, data, fluid, explosion, mygrids, cigarette and filecache.
6% of all VDB files start with the magic bytes 202, which are always the first bytes of this file format. These are binary files, so they do not contain words or text. The files are on average 1 MB in size and range from 170 bytes to 10 MB. The keywords V01.01 are typical for these files. Files like these are sometimes connected to reset, porsche, benz and opel.

The remaining 54% of all VDB files are different files with different signatures, such as Dr.Web Anti-Virus Database, VistaDB database, SQL, JetDB, XML, SymiscVedis, VDB and SOPH. The category is xvdl, fleetdb, output, mist, vehicle, gruppe, bunny or fire.

How to solve problems with VDB files

Associate the VDB file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest VDB file format. Search, therefore, e.g. on the manufacturer website after an available Houdini update.
To make sure that your VDB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
