When people refer to an "X file," they generally 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 might mean different things, most commonly a legacy DirectX model format or a Lex lexer source file, and the simplest way to identify yours is to consider whether it came from a 3D/game project or a programming toolchain and then open it in a plain text editor to see if it contains DirectX-style headers like older `xof` text markers with mesh and material structures or Lex-style code with `%%` sections or `%{ ... %}` blocks.
If the file displays binary-looking output in Notepad, it may be a binary build, but scanning for DirectX-style markers like `Mesh` or Lex-like rule tokens can still help, and you should make sure Windows isn’t hiding extensions by enabling "File name extensions" under File Explorer → View, because a file that appears to be `something.x` could actually be `something.x.txt` or even `something.x.exe`, which changes its real identity.
The `.x` file extension can span different uses since extensions are simply naming habits, and with no master authority to prevent duplication, various industries can reuse the same suffix, so `.

Another reason is that an extension often represents a range of related file types rather than one strict standard, and some formats even come in multiple encodings such as text or binary, so you can encounter very different-looking `.x` files within the same ecosystem; meanwhile, Windows relies on simple file associations instead of deeply analyzing contents, meaning the same `.x` file might open in a 3D tool on one machine and a text editor on another, and because extensions are easy to rename—on purpose or by accident—you can also end up with files whose true contents don’t match the label at all.
Because of all that, the most reliable way to figure out what a `.x` file means is to rely on context clues—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` can mean different things is that file extensions are not strict standards rather than universal rules, so different communities can reuse the same short extension—especially one-letter ones—for totally unrelated formats, and because operating systems rely on file associations instead of deeply inspecting a file’s contents, the same `.x` file might open in a 3D program on one computer and a text editor on another, making it seem like the extension itself has multiple meanings.
Some `.x` ecosystems have multiple encoding types, including text and binary options, so even closely related `.x` files can look wildly different in Notepad, and since extensions are simple to rename, the label may not reflect the real data—so checking the file’s origin and briefly inspecting its contents is the safest way to verify its identity.
