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 describe 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 file typically involves importing it into the correct 3D workflow—such as bringing it into Autodesk 3ds Max through its animation tools or loading it into a Cal3D-compatible pipeline—and mismatches in bone names, hierarchy, or proportions can cause the motion to fail, appear twisted, or shift incorrectly, so checking the file in a text editor for hints like “Cal3D” or references to 3ds Max/Biped/CAT lets you determine which software should import it and what matching rig you’ll need.

An XAF file is dedicated to animation data rather than complete character assets, typically holding timelines, keyframes, and tracks that drive bone rotations or other transforms tied to specific bone names or IDs, often with interpolation curves for smooth motion, and depending on the pipeline it may store one animation or many while always defining skeletal movement over time.

An XAF file typically lacks everything required to display a finished animation, offering no geometry, materials, textures, lights, or cameras and often not providing a full rig definition, instead assuming you already have the proper skeleton loaded, so by itself it’s just choreography without a performer, and importing it onto mismatched rigs—those with different bone names, structures, orientations, or proportions—can break the animation or distort it with twists and offsets.

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 suggest 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 reveal a 3ds Max–style pipeline along with familiar bone-naming patterns.

If the content contains clear “Cal3D” references or tag patterns that mirror Cal3D animation structures, it’s almost certainly Cal3D XML needing corresponding skeleton/mesh files, while abundant transform tracks and rig-mapped identifiers imply a 3ds Max origin, and a streamlined runtime-friendly layout leans in favor of Cal3D, making related assets and the first portion of the file useful context clues for verifying the exporter.
