An XAF file is typically an XML-based animation format used in 3D workflows, often as a 3ds Max or Cal3D XML animation file, and its role is to store motion data rather than full characters or scenes, so opening it in a text editor like Notepad shows structured tags and numbers that outline keyframes, timing, and bone transforms without actually “playing,” meaning it holds the choreography of animation tracks but does not include meshes, textures, materials, lights, or cameras and assumes a compatible rig already exists.
“Opening” an XAF is generally done by importing it into the right 3D system—whether that’s Autodesk 3ds Max using its rigging tools or a pipeline that supports Cal3D—and if the bone setup doesn’t match, the animation may not apply or may look distorted, making it useful to inspect the beginning of the file in a text editor for terms like “Cal3D” or 3ds Max/Biped/CAT to figure out which program expects it and what skeleton it must pair with.
An XAF file stores purely animation data rather than models or scene details, offering timelines, keyframes, and transform tracks that rotate or move bones identified by names or IDs, often including smoothing curves, and it may house a single action or multiple clips but consistently describes the skeleton’s progression through time.

An XAF file typically avoids including the visual components of animation such as meshes, textures, materials, lights, or cameras, and generally doesn’t offer a standalone skeleton, assuming the correct rig is preloaded, so by itself it acts as choreography without a performer, and importing it into a rig with mismatched naming, hierarchy, orientation, or scale can cause failures, distortions, twisting, or offset motion since the animation tracks can only match what aligns properly.
To identify what kind of XAF you have, the quickest approach is to think of it as a self-describing clue file by opening it in a plain text editor such as Notepad or Notepad++ and checking whether it’s readable XML, since visible tags and words indicate an XML-style animation file, while random symbols might mean it’s binary or misnamed, and if it is readable, scanning the first few dozen lines or searching for terms like Max, Biped, CAT, or other rig-related wording can hint at a 3ds Max–style pipeline along with familiar bone-naming patterns.
If you find explicit Cal3D wording or XML attributes that define Cal3D clip/track structures, you’re likely looking at a Cal3D XML animation that expects matching Cal3D skeleton and mesh files, whereas detailed DCC-style transform tracks and familiar rig identifiers tend to match a 3ds Max workflow, and efficient game-oriented clip formats signal Cal3D; external associated files and especially the first lines of the XAF provide the strongest confirmation.
