A “VS file” usually designates 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 `float4` and semantics such as `POSITION`, or GLSL with `uniform` shaping `gl_Position`.
Because the `.vs` extension isn’t restricted to one meaning, the file might be custom text or binary, and if it looks unreadable the most reliable identification method is checking its Windows file-association info; but a folder named `.vs` next to a `.sln` file is simply Visual Studio’s cache directory containing workspace configuration, not real project code, and while it’s excluded from Git, deleting it is usually safe since Visual Studio rebuilds it—at the cost of losing local UI state like tab sets.
“.vs” can mean something else because file extensions are not globally coordinated, and Windows uses them mainly for launch associations rather than meaning, allowing developers to repurpose `.vs` for unrelated tasks, which is why not every `.vs` file will be a vertex shader even though that usage is well-known in graphics; a different tool could assign `.vs` to its vector-scene format, and Windows would still show it as a generic “VS file” unless a program registers ownership.
A `.vs` file can also be “something else” because its usage scenario determines what the extension actually signals; in graphics work `.vs` typically hints at a vertex shader due to its placement beside `.ps` or `.

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.
