A "VS file" usually refers to something ending in the `.vs` extension, though the term can also describe Visual Studio’s `.vs` folder, so the meaning depends on how it appeared in your workflow; if it’s truly a `name.vs` file, it’s most often a vertex shader script used in graphics pipelines, typically written as plain text that opens fine in editors like VS Code or Visual Studio, and its contents may resemble HLSL with elements like `float4` and semantics such as `SV_Position`, or GLSL with items like `#version` and assignments to `gl_Position`.

Since the `.vs` extension isn’t standardized across applications, it might be a program-specific text or binary file, and unreadable characters usually mean you should check the program that made it to identify it; however, a folder literally named `.vs` beside your `.sln` file is Visual Studio’s local workspace/cache, holding indexes 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 labels, not enforced standards, and Windows uses them just to decide which program to open rather than enforcing unique meanings, so any developer can reuse the same extension for unrelated purposes, which is why you can’t assume every `.vs` file is a vertex shader even though that’s common in graphics, since another tool might use `.vs` for its own project file and Windows would still show it as a "VS file" or unknown unless something on your PC has claimed that extension.

A `.vs` file can also be "something else" because context drives interpretation; in rendering pipelines `.vs` commonly represents a vertex shader due to neighboring `.

If you want a quick confirmation of what your `.vs` file actually signifies, treat the extension as just a hint and validate through evidence: check where the file sits and what’s around it, review its "Opens with" details, and open it in a text editor to see if it looks like shader code, some other text structure, or binary—those steps nearly always give you the answer quickly.
