A "VS file" typically indicates a `.vs` extension file, but since some people also label Visual Studio’s `.vs` folder this way, its meaning relies on how it’s being referenced; if it really is a `.vs` file, it’s usually a vertex shader script for rendering pipelines, stored as plain text you can open in typical editors, and its code may mimic HLSL with constructs like `cbuffer` plus semantics such as `SV_Position`, or GLSL with `uniform` feeding into `gl_Position`.

Since the `.vs` extension can refer to different file types, it might be a program-specific text or binary file, and unreadable characters usually mean you should check its origin to identify it; however, a folder literally named `.vs` beside your `.sln` file is Visual Studio’s local workspace/cache, holding IntelliSense caches rather than source code, and while you wouldn’t commit it to Git, removing it is typically fine because Visual Studio regenerates it—though you’ll lose some local preferences like open documents.

".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 `.

A `.vs` file can also be "something else" because context tells you the real meaning; in rendering pipelines `.vs` commonly represents a vertex shader due to neighboring `.ps`/`.fs` files and shader-compilation steps, while in other workflows the same extension can label a readable config or script using custom formatting instead of HLSL/GLSL, and sometimes it’s binary, appearing unreadable because it’s a compiled asset or proprietary container, so the only reliable indicator is its origin and the software that can load it.

If you want a quick way to confirm what your particular `.vs` means, the fastest method is to treat the extension as a hint and verify it by evidence: check the folder context and neighboring files, review the file properties for "Opens with," and open it in a text editor to see whether it contains shader-style code, another readable format, or binary data—those three steps usually reveal the truth in minutes.
