An XAF file is most commonly 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 define keyframes, timing, and bone transforms without actually "playing," meaning it holds the choreography of animation tracks but excludes meshes, textures, materials, lights, or cameras and assumes a compatible rig already exists.
To "open" an XAF, you generally import it into the appropriate 3D pipeline—like 3ds Max with its rigging tools or any Cal3D-capable setup—and mismatched bone names or proportions often result in broken or offset animation, so checking the header in a text editor for clues such as "Cal3D" or mentions of 3ds Max/Biped/CAT helps pinpoint which program it belongs to and what skeleton should be used with it.
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.

XAF file viewer, you could call us at our web-page. An XAF file tends not to include geometry, textures, shading materials, or scene elements, and often doesn’t define a complete skeleton on its own, expecting the target software to have the proper rig in place, which makes the file function more as choreography than a full animation, and when the destination rig differs in bone naming, structure, orientation, or proportion, the animation may refuse to apply or appear misaligned, twisted, or offset.
To determine the XAF’s origin, the fastest move is to treat it as a clue file by opening it in Notepad or Notepad++ and checking whether it’s readable XML, because structured tags imply an XML animation format while random symbols may be binary, and if readable, scanning the header or using Ctrl+F for Max, Biped, CAT, Autodesk, or
familiar bone names can indicate a 3ds Max–style animation pipeline.
If the content contains clear "Cal3D" references or tag patterns that match Cal3D animation structures, it’s almost certainly Cal3D XML needing corresponding skeleton/mesh files, while abundant transform tracks and rig-mapped identifiers indicate 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.
