When someone mentions an "X file," they generally mean a file ending with `.x`, the extension after the final dot like `model.x`, which gives the OS a rough idea of how to open it just as `.pdf` or `.zip` do, but because file extensions are only naming conventions, they can easily be changed or reused by different software, making them unreliable at times.
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 0303txt` plus mesh/material data, or instead looks like Lex code with `%%` separators or `%{ ... %}` embedded code.
If the file looks like random bytes when opened in Notepad, it could be a binary variant, yet searching for recognizable phrases like `Material` may still identify DirectX-like data, while Lex-oriented files may contain token-style patterns, and enabling real extension display in Windows (File Explorer → View → "File name extensions") helps avoid confusion when a file that looks like `something.x` is actually `something.x.txt` or `something.x.exe`, changing what it truly is.
An extension such as `. Here is more info about

standardized identifiers, and with no organization blocking duplication, groups can adopt the same extension for unrelated purposes—like `.x` in old DirectX modeling and `.x` in lexer tooling—especially with short names where limited sequences led to inevitable collisions.
Another reason is that an extension often represents a broader family of files 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 best way to identify a `.x` file in your situation is to use what workflow produced it plus a fast content inspection by opening it in a text editor and searching for meaningful headers or terms, and if you provide the first 10–20 lines or say which program it came from, I can tell you precisely which `.x` format you have.
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` definitions include different flavors, 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.
