An XAF file is intended to be an XML-based animation container in 3D workflows, such as those in 3ds Max or Cal3D, storing movement information instead of full character assets, so opening it in a text editor reveals structured XML with numbers describing timing, keyframes, and bone transforms that don’t "play," and the file contains only animation tracks while omitting meshes, textures, materials, and other scene data, requiring a compatible rig to interpret it.

"Opening" an XAF file most often requires 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 is a quick way to confirm which software should import it and what matching rig you’ll need.

An XAF file is best understood 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 rarely contains the visual elements of an animation like meshes, textures, materials, or scene components, and often lacks a full independent skeleton definition, assuming the correct rig already exists, which is why the file alone feels more like movement instructions than a complete performance, and why incorrect rig matches—due to different naming, hierarchy, orientation, or proportions—lead to broken or distorted results.

To identify what XAF you’re dealing with, the quickest trick is to rely on a self-describing text check by opening it in a simple editor and seeing if the content is readable XML—tags and meaningful words indicate XML, while messy characters suggest binary or a misleading extension—and if it is XML, skimming the first lines or searching for terms like Max, Biped, CAT, or Character Studio plus recognizable rig naming can point to a 3ds Max workflow.

If the file contains "Cal3D" markers or XML attributes that resemble 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 suggest 3ds Max workflows, and a compact game-oriented clip layout often signals Cal3D, with surrounding files offering hints and the header lines giving the clearest indication of the exporter.
