An .XOF file varies depending on the software that created it and usually appears either as a DirectX-lineage 3D model file containing mesh data, materials, UVs, and possibly animation, or as an OthBase XML file storing Othello games with metadata; readable "xof …" headers or binary noise hint at the 3D variant, whereas clean XML with structured tags points to the OthBase version, making a text-editor preview the quickest test.

When people say "XOF is a 3D graphics file," they mean it stores the building blocks of a 3D model—not a flat image—because in the older RenderMorphics/Microsoft/DirectX ecosystem, XOF acted as a container for meshes, normals, UVs, materials, frames, and sometimes animation, saved in either readable text with keywords like Mesh/Material or as binary, and modern workflows usually import/convert it to FBX/OBJ/GLTF, with the quickest identification method being to open it and check for an "xof …" header or 3D-style sections rather than XML from unrelated software.

To quickly tell what kind of .XOF file you have, look at its origin and what shows up when opened as text: files tied to 3D packs, mods, or DirectX workflows tend to be the 3D/XOF variety, whereas files from Othello tools or OthBase tend to be XML; readable XML starting with `<?xml ...?>` confirms the OthBase type, while headers beginning with `xof` or 3D terms like Mesh, Frame, or TextureFilename—or messy binary with "xof" visible—point to the 3D format, and these fast checks typically identify it without extra tools.

When we say "XOF is a 3D graphics file," we’re pointing out that it stores model data—not a flat photo—and in older DirectX-era pipelines it functioned like an X-file container holding mesh vertices and faces, normal vectors for lighting, UV coordinates for texture placement, and material info such as diffuse color, gloss, transparency, and texture paths.

Depending on how it was exported, it can also include scene hierarchy info that defines how model parts relate to each other, and sometimes even animation data, with the file stored either as readable text—showing recognizable keywords in a text editor—or as binary, which looks scrambled even though it holds the same 3D structures underneath For more information in regards to XOF file description review the web-site. .
