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 how it was referenced 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 `SV_Position`, or GLSL features like `vec3` that feed 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 Windows “Opens with” properties to identify it; however, a folder literally named `.vs` beside your `.sln` file is Visual Studio’s local workspace/cache, holding user session settings 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 session history.

“.vs” can mean something else because file extensions are just identifiers, with Windows treating them mainly as hints for which application should open them, leaving developers free to reuse the same extension in completely different ways, so not every `.vs` file should be assumed to be a vertex shader even if that’s widespread in graphics work; another app could assign `.vs` to its own internal project, and Windows would still call it a “VS file” unless a program on your machine has associated with it.

A `.vs` file can also be “something else” because context defines what the extension is signaling; in game or rendering pipelines `.vs` often means “vertex shader” since it appears beside `.ps` or `.

If you want a quick way to confirm what your particular `.vs` means, the fastest method is to treat the extension as a clue 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.
