An XAF file works as an XML animation format for tools like 3ds Max or Cal3D, dedicated to motion rather than full character assets, which is why opening it in a text editor displays XML tags full of numeric values for per-bone transforms, timing, and keyframes that don’t animate by themselves, and the file provides animation tracks but doesn’t include geometry, materials, textures, or scene elements, expecting an existing skeleton inside the target application.

To “open” an XAF, you normally 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 you verify which program it belongs to and what skeleton should be used with it.

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 usually doesn’t carry 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 view 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 hint at a 3ds Max–style pipeline along with familiar bone-naming patterns.

If the file contains “Cal3D” markers or XML attributes that look like Cal3D animation tracks, it’s probably a Cal3D-format XML expecting the correct skeleton/mesh pair, while detailed per-bone transform data and rig-style identifiers tend to imply 3ds Max workflows, and a compact game-oriented clip layout leans toward Cal3D, with surrounding files offering hints and the header lines giving the clearest indication of the exporter.
