When people refer to an "X file," they usually mean a file whose name ends in `.x`, the suffix after the last dot such as in `model.x`, which helps Windows or macOS guess what program should open it, similar to how `.pdf` or `.zip` identify their file types, though this system isn’t foolproof since extensions can be changed or reused for completely different formats.
A `.x` file may refer to both legacy DirectX 3D assets and Lex lexer source files, so the most direct way to figure out which one you have is to think about where it originated and open it in Notepad or Notepad++ to see whether it contains DirectX text markers like `xof 0302txt` plus mesh/material data, or instead looks like Lex code with `%%` separators or `%{ ... %}` embedded code.
If you see unreadable gibberish in Notepad, the file is likely a binary type, though checking for strings such as `TextureFilename` can still reveal DirectX origins, or searching for rule-oriented text can hint at Lex, and it’s smart to ensure Windows shows genuine extensions through File Explorer → View → "File name extensions," since an apparent `something.x` might really be `something.x.txt` or `something.x.exe`, affecting how you handle it.
The `.x` extension can describe unrelated file types because extensions are loosely agreed hints instead of strict global standards, so nothing stops multiple communities from reusing the same suffix: a 3D workflow may use `.x` for DirectX models while programming ecosystems use it for lexer sources, a pattern increasingly common for short extensions where early widespread use caused overlaps.
Another reason is that an extension typically identifies a cluster of related types rather than one strict schema, and many formats include both text-based and binary flavors, so `.x` files can look drastically different even inside one workflow; combined with Windows’ reliance on extension-based associations instead of reading the file’s structure, a `.x` file may open in a 3D viewer on one computer and a text editor on another, and because extensions can be renamed without changing the underlying data, mismatches between label and content are common.
Because of all that, the most reliable way to figure out what a `.x` file means is to rely on where it originated—such as what you downloaded it for or which files sit next to it—and to perform a quick content check by opening it in a text editor and scanning for recognizable headers or keywords, and if you share the first 10–20 lines or mention the software involved, I can identify exactly which `.x` type it is.
The reason `.x` has multiple interpretations is that file extensions are flexible labels, enabling separate ecosystems to pick identical short extensions for different formats, and because operating systems don’t determine file type by analyzing the data but by following file associations, one `.x` file might open differently across computers, creating the feeling that `.x` means different things.
