A "VS file" usually means you’re dealing with a `.

Because the `.vs` extension isn’t bound to one official format, a `.vs` file may be plain text or binary depending on the software, and if it appears unreadable the right approach is checking its origin; but a folder named `.vs` next to a `.sln` file is Visual Studio’s cache directory containing indexes, not actual source files, and should be excluded from Git, with deletion generally safe since Visual Studio rebuilds it—though this resets local preferences such as window arrangements.

".vs" can mean something else because file extensions aren’t controlled by any authority, and Windows mostly uses them as a cue for file association rather than meaning, so developers can adopt `.vs` for anything they like, which is why you can’t automatically treat every `.vs` file as a vertex shader despite its popularity in graphics, since another piece of software might use `.vs` for vector-scene data and Windows will still display it generically unless a program has registered the extension.

A `.vs` file can also be "something else" because context changes what the extension is signaling; in game or rendering pipelines `.vs` often means "vertex shader" since it appears beside `.ps` or `.fs` files in shader folders and gets compiled in the build, but in other workflows the same extension might be reused for a text-based config or script that opens cleanly yet looks nothing like HLSL/GLSL—maybe JSON—and sometimes a `.vs` file is binary, showing garbled characters because it’s a compiled asset, cache, or proprietary container, meaning you must rely on its source and the program that can open it to know its real purpose.

If you want a rapid way to verify the meaning of your `.vs` file, use the extension only as a hint 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.
