An .XOF file can refer to unrelated file structures, most notably as a DirectX-family 3D model format or as an OthBase XML file; the 3D version may include meshes, materials, texture references, and sometimes animation, showing headers like "xof …," while the OthBase version is plain XML holding Othello move lists and metadata, making a quick text-editor look—XML versus xof header/binary—the fastest identification method.

When people say "XOF is a 3D graphics file," they’re saying it contains the necessary info for rendering 3D models in the legacy DirectX ecosystem, including meshes, normals, UV layouts, materials, frame hierarchies, and sometimes animation, stored as readable ASCII or binary, and because newer tools vary in compatibility, users often convert it to FBX/OBJ/GLTF, confirming its type by looking for an "xof …" header or 3D sections in a text editor.

To quickly tell what kind of .XOF file you have, start with basic simple observations: if the file came from a 3D pipeline, DirectX-era assets, or older game mods, it’s likely the 3D/X-file family, but if it came from Othello/OthBase tools or game databases, the XML variant is far more likely; opening it reveals more—clean XML with tags like `<?xml ...?>` means the OthBase format, while an opening header starting with `xof` or terms such as Mesh or Material, or binary noise with "xof" at the top, indicates the 3D type, and these hints usually settle the question quickly.

When we say "XOF is a 3D graphics file," we’re emphasizing that it represents 3D content rather than storing a photo, and in classic Windows/DirectX workflows it acted as an X-file-style container for vertices, triangles, normal vectors, texture-mapping UVs, and material parameters such as color, shininess levels, transparency, and links to texture images.

Depending on the export method, it may also contain node-based scene structure describing how pieces of the model are arranged, plus occasional animation details, and the file might be saved in text form—where clear section labels appear—or in binary form, which looks like gibberish despite representing the same internal 3D elements.
