A “VS file” is most often referring to a `.vs` extension, but because people also use “VS” to mean Visual Studio’s `.vs` folder, interpretation relies on the environment you found it in; if it’s truly a `.vs` file, it’s commonly a vertex shader script written in plain text for rendering, readable in editors like VS Code, and may look like HLSL with `float4x4` and semantics such as `TEXCOORD`, or GLSL with `uniform` shaping `gl_Position`.

The `.vs` extension isn’t globally standardized, so the file could be custom text or binary and unreadability just means you must rely on which program created it to determine its role; meanwhile, a `.vs` folder sitting by a `.sln` file is Visual Studio’s workspace/cache holding user layout data rather than your code, and since it shouldn’t go into Git, deleting it is a common fix—Visual Studio will recreate it, though you’ll lose local session details like window layout.

“.vs” can mean something else because file extensions don’t enforce a single definition, and Windows mostly uses them as a cue for file association rather than meaning, so developers can adopt `.

A `.vs` file can also be “something else” because the project environment determines what the extension actually signals; in graphics work `.vs` typically hints at a vertex shader due to its placement beside `.ps` or `.fs` files under shader directories, but another tool might adopt `.vs` for text-based configs or scripts that remain readable yet have none of the HLSL/GLSL structure—showing JSON instead—and it may also be binary, displaying gibberish because it’s a compiled or cached asset, meaning the safest clues come from where the file originated and which program opens it correctly.

If you want a fast way to figure out what your `.vs` file actually is, treat the extension as a loose signal and verify it by checking the folder and nearby files, reviewing its “Opens with” info, and opening it in a text editor to see if it looks like shader code, another text format, or binary—these three checks typically answer the question quickly.
