A “VS file” is often understood as a `.vs` text file, but since many also call Visual Studio’s `.vs` folder “VS,” you must rely on context 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 `cbuffer` with semantics such as `POSITION`, or GLSL features like `uniform` that feed into `gl_Position`.
Because the `.vs` extension doesn’t enforce one defined format, it may be a custom text or binary file from a specific application, and if its contents look garbled the best clue is the Windows “Opens with” info; on the other hand, if you’re looking at a folder named `.vs` next to a `.sln` file, that’s Visual Studio’s cache folder containing IntelliSense databases, not your code, so it’s normally excluded from Git and safe to delete because Visual Studio recreates it—though doing so resets local state like personal layout choices.
“.vs” can mean something else because file extensions are just loose markers, 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 context changes what the extension is signaling; in game or rendering pipelines `.

If you want a rapid way to verify the meaning of your `.vs` file, use the extension only as a rough guide and back it up with evidence: examine its folder context and surrounding files, check the file’s “Opens with” field, and open it in a text editor to see whether it resembles shader code, another readable format, or binary, which almost always resolves the mystery fast.
