An .XOF file can belong to two unrelated worlds—one being an older DirectX-related 3D format holding geometry, normals, UV coordinates, materials, and texture names, sometimes flagged by "xof … txt …" or "xof … bin …," and the other being OthBase’s XML game record format for Othello, which stores moves and metadata; opening the file to check for XML versus a DirectX-style header or binary is the simplest way to know which is which.

When people say "XOF is a 3D graphics file," they mean it includes the data required to describe 3D shapes—like meshes, normals, UVs, materials, and sometimes frames or animation—from the older DirectX-era format, which may appear in ASCII with clear keywords or in binary, and because of aging toolchains, a common approach is to import/convert it to FBX/OBJ/GLTF, with the fastest verification being a text-editor check for an "xof …" header or model-related structures.

To quickly tell what kind of .XOF file you have, start with basic quick checks: 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 the data behind a 3D object 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 how it was created, it may include a node hierarchy along with possible animation data, and the format might appear as readable text—showing obvious sections—or as binary, which displays as nonsense characters even though the same model structures are embedded inside Here is more info regarding XOF file format review the website. .
