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 mean it includes the content necessary 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, you can use simple forensics like its origin and how it appears in a text editor, since a file from a 3D asset pack, old game/mod, or DirectX workflow usually signals the 3D/X-file type, while one from an Othello database or OthBase tool points to the XML game-record variant; opening it in Notepad or Notepad++ and seeing readable XML beginning with `<?xml ...?>` indicates the OthBase style, while a top line starting with `xof` or keywords like Mesh, Material, Frame, TextureFilename—or unreadable binary paired with "xof" near the start—strongly suggests the 3D family, and these quick steps normally identify the format before searching for converters.

When we say "XOF is a 3D graphics file," we mean it’s a container for the structural parts of a 3D model rather than a flat picture, and in older Windows/DirectX pipelines it followed the legacy X-file style by storing meshes made of vertices and triangles, normals for lighting, UV coordinates for texture mapping, and materials describing color, shine, transparency, and linked texture filenames.

Here's more about XOF file editor look at the page. Depending on how it was generated, it might also store grouping/positioning frames that define part relationships and sometimes animation data, and it can be written as plain text—readable with visible keywords—or as binary, which appears scrambled even though it encodes the same underlying 3D content.
