A “VS file” is generally a shorthand for a `.vs` extension, though the same phrase can also refer to Visual Studio’s `.vs` folder, making the correct meaning depend on how you encountered the file; when it’s an actual `.vs` file, it’s typically a vertex shader text file readable by editors, containing HLSL elements like `cbuffer` with semantics such as `SV_Position`, or GLSL patterns such as `vec3` updating `gl_Position`.
Because the `.vs` extension isn’t a predefined standard, 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 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 window layouts.
“.vs” can mean something else because file extensions are simply open labels, with Windows relying on them only to match files to programs, letting different developers adopt `.vs` for various internal purposes, so assuming that all `.vs` files are vertex shaders isn’t reliable even though it’s common in graphics; another application might use `.vs` for its own vector-scene content, and Windows will still list it as a “VS file” unless some installed software has taken over the association.
A `.vs` file can also be “something else” because context affects the meaning; in rendering projects `.vs` is often understood as a vertex shader due to its association with other shader files and build steps, yet other workflows reuse `.

If you want to quickly determine what your `.vs` file means, think of the extension as a non-binding label and confirm by evidence: look at its folder neighbors, inspect the file properties for “Opens with,” and open it in a text editor to check whether it’s shader code, some other readable syntax, or binary junk—usually enough to identify it in under a minute.
