An XAF file serves mainly as 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 helps identify which software should import it and what matching rig you’ll need.
An XAF file is generally an
animation-only asset that holds the data needed to move a rig but not the character or scene, containing the "motion math" such as timelines, keyframes, and tracks that apply rotations—and sometimes position or scale—to named bones or IDs, along with interpolation curves for smooth transitions, whether it represents one action like a walk cycle or multiple clips, all describing how a skeleton changes over time.
An XAF file typically avoids including the visual components of animation such as meshes, textures, materials, lights, or cameras, and generally doesn’t offer a standalone skeleton, assuming the correct rig is preloaded, so by itself it acts as choreography without a performer, and importing it into a rig with mismatched naming, hierarchy, orientation, or scale can cause failures, distortions, twisting, or offset motion since the animation tracks can only match what aligns properly.
To figure out what kind of XAF you have, the quickest strategy is to treat it like a clue-filled text file by loading it into Notepad or Notepad++ and checking whether it’s valid XML, because readable tags imply an XML animation format while random characters may mean binary data or a misused extension, and if it is readable, searching early lines for keywords like Max, Biped, CAT, or Character Studio as well as common bone names can quickly confirm if it comes from a 3ds Max pipeline.

If the content contains clear "Cal3D" references or tag patterns that align with 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 leans in favor of Cal3D, making related assets and the first portion of the file useful context clues for verifying the exporter.
