An XAF file is best understood as an XML animation file used by systems like 3ds Max or Cal3D to store movement rather than full 3D characters, so when opened in a text editor it shows XML tags with numeric keyframes, timing, and joint transforms that cannot animate on their own, providing choreography only and not bundling geometry, materials, or scene elements, and depending on a matching skeleton in the destination software.
“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 mainly serves as an animation-focused asset that provides motion instructions rather than full models or scenes, storing things like timing, keyframes, and transform tracks that rotate or shift specific bones identified by names or IDs, often including interpolation data for smooth movement, and depending on the workflow, it may contain a single animation or several clips but always defines how a skeleton moves through time.

An XAF file doesn’t normally pack 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 identify what kind of XAF you have, the quickest approach is to treat it like 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 reveal a 3ds Max–style pipeline along with familiar bone-naming patterns.
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 suggest a 3ds Max origin, and a streamlined runtime-friendly layout often corresponds to Cal3D, making related assets and the first portion of the file useful context clues for verifying the exporter.
