A "VS file" typically corresponds to a `.vs` text file, but since many also call Visual Studio’s `.vs` folder "VS," you must rely on where the file came from to know for sure; if it’s truly a `.vs` file, it’s most commonly a vertex shader source used alongside other shader stages, opening normally in text editors, and containing HLSL traits like `float4x4` with semantics such as `POSITION`, or GLSL features like `#version` that feed into `gl_Position`.

Because the `.vs` extension varies depending on software, the file might be custom text or binary, and if it looks unreadable the most reliable identification method is checking the workflow it came from; but a folder named `.vs` next to a `.sln` file is simply Visual Studio’s cache directory containing indexes, 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 session arrangements.

".vs" can mean something else because file extensions exist only as naming conventions, 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 project bundle, 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 the surrounding context 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 XML 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 need to quickly identify what your `.vs` file represents, the best tactic is to use the extension as a rough indicator and confirm through evidence: look at surrounding files and folder context, inspect the "Opens with" field in file properties, and open it in a text editor to see whether it’s shader code, some other readable text, or binary, which almost always clarifies its purpose quickly.
