When people talk about an "X file," they often mean a file labeled with the `.x` extension, the portion after the last dot such as in `model.x`, intended to help Windows or macOS identify what kind of file it is similar to `.

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 `xof 0302txt` with mesh and material structures or Lex-style code with `%%` sections or `%{ ... %}` blocks.
If the file appears as unreadable data in Notepad, it may be a binary version, and you can still try searching for readable hints inside it such as `TextureFilename` for DirectX-style content or rule-based terms for Lex-related material, and it’s also wise to confirm that Windows is showing actual extensions through File Explorer → View → "File name extensions," since a file that seems to be `something.x` might really be `something.x.txt` or even `something.x.exe`, which affects how you should treat it.
A lone extension like `.x` can have multiple meanings because extensions are simply conventional, and without a global system preventing overlap, different fields can independently claim the same suffix, allowing `.x` to refer to DirectX-era 3D models in one ecosystem and lexer files in another, a problem made common by short extensions where early adoption caused widespread reuse.
Another reason is that an extension often covers a variety of format variants instead of one exact structure, and some formats have both text and binary encodings, causing `.x` files to vary within the same environment; added to that, Windows depends on file associations rather than true content analysis, which means the same `.x` file may launch different software on different systems, and since extensions are simple to rename, you can encounter files whose internal data doesn’t align with the extension.
Because of all that, the most dependable method for understanding a `.x` file is to combine context with a simple content test by viewing it in a text editor and looking for distinctive markers or keywords, and if you paste its first 10–20 lines or describe the project it’s part of, I can identify the exact `.x` variant.
The reason `.x` can denote unrelated formats is that extensions are not universal standards, so two independent communities can select the same one-letter suffix without conflict, and because operating systems rely on associations rather than deep inspection, a `.x` file can open in a 3D application on one system and a text editor on another, making its meaning appear inconsistent.
Some `.x` definitions include different encodings, such as binary and text forms, which can make two related `.x` files appear drastically different in a text editor, and because renaming extensions is trivial, you might encounter files with mismatched contents, making context plus a quick peek inside the file the most dependable way to confirm what `.x` you’re dealing with.
