When someone mentions an "X file," they typically 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 0302txt` plus mesh/material data, or instead looks like Lex code with `%%` separators or `%{ ... %}` embedded code.
If the file appears as nonsense in Notepad, it may be a binary version, and you can still try searching for readable hints inside it such as `Material` 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 single extension like `.x` ends up with multiple meanings because file extensions are nonstandard labels, not globally governed identifiers, which means any group can adopt the same suffix—letting `.x` serve DirectX model formats in 3D pipelines while also representing lexer source files in development tools—something that happens frequently with short extensions whose small set of options encourages collisions.
Another reason is that an extension often covers a family of loosely related formats instead of one exact structure, and some formats have both text and binary encodings, causing `. If you liked this information and you would want to obtain more info concerning

Because of all that, the surest approach to interpreting a `.x` file is to use where it was obtained together with a quick text-editor check for familiar headers or patterns, and if you share the initial 10–20 lines or note the software source, I can determine which `.x` type applies.
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.
Some `.x` formats appear in different encodings, including text and binary versions, meaning two related `.x` files can look nothing alike in a text editor, and since extensions can be changed so easily, you may find files where the extension doesn’t match the real data, making context and a brief content check the most reliable way to determine what `.x` type you have.
