What is a FBX file?

A .FBX file is an Autodesk Kaydara FilmBox Digital Content file.

The .fbx file extension is a proprietary file format initially developed by Kaydara. Autodesk bought the license for the file format late 2006 and has been its owner since then. The .fbx format originated as a replacement file format for Canadian company Kaydara's Filmbox- software for recording data from motion capture devices.

Filmbox is shortened to FBX. Hence, it became a file extension for 3Ds and video-related content. The FBX's primary purpose is to provide interoperability between digital content creation applications. The .fbx files allow computer-based creations to be opened, edited, and modified across many applications and systems. FBX is also part of Autodesk Gameware, a series of video game middleware.

FBX files can be converted from .obj, .dxf, .3ds, and .dae formats using the free FBX conversion utility.The FBX can be represented on disk as either binary or ASCII data. The ASCII format is a tree-structured document with clearly named identifiers. FBX files can work with many 3D authoring tools and software.
