What is a .X file?
The .x format held 3D models and animation for Microsoft’s DirectX.
- Did you know
- The .x mesh format was widely used by games built on early DirectX.
- The .x mesh format debuted with DirectX 2.0 and is template-driven, letting applications define their own data types alongside meshes and animation.
- Microsoft deprecated the .x format after Direct3D 9, dropping it from Direct3D 10 and later.
- What Analyser reads
- Identify more 3D, CAD and scene files: Google Draco compressed meshes, Gaussian splats (KSplat), Universal 3D, Dassault 3DXML, DirectX .x models, Qubicle voxels, Wings3D, Autodesk Revit (RVT/RFA and templates, build version from BasicFileInfo), Siemens Solid Edge, Navisworks, legacy CATIA V4, terrestrial-scanner point clouds (FARO/Trimble) and legacy binary Visio (.vsd).
- Depth of analysis
- .X is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .X file
- Drag a .X file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
