A .VSH file is generally recognized as a vertex shader source file in 3D pipelines, where it runs on the GPU to move vertices through matrix transforms and deliver items such as texture data, normals, or color data downstream, though the extension can also appear in engines that reuse `.vsh` for project-specific structures.

To confirm what your .VSH file really is, the quickest method is to inspect it directly in a text editor and look for shader-like syntax—GLSL hints like `varying` or `gl_Position`, or HLSL indicators such as `mul(...)` along with semantics like `SV_Position`—and then study its folder placement, especially if it appears in directories such as `materials` or alongside files like `.fsh` or `.

If you see strange blocks instead of clear shader code when opening the file, it may be a compiled binary such as a shader blob or a sealed engine asset, and identifying it works best by using the `.VSH` extension as a starting clue while verifying through content inspection, checking adjacent files and folders, and locating project references that load it, since these steps typically pinpoint its real function.

The ".vsh" extension is mainly a convenience rather than a strict standard, giving developers an easy way to recognize shader stages by sight, where "v" implies vertex and "sh" implies shader, making it clear that the file holds vertex-shader code and helping pair it with matching files like .fsh for fragment shaders so their roles in the pipeline are immediately understood.

Another reason ".vsh" is used is tied to the way engines treat shaders because build systems and asset pipelines look for certain extensions to auto-compile shader files, and even though GLSL/HLSL are text, a dedicated extension ensures the correct processing stage applies; different communities standardized on suffixes like .fx/.shader, and ".vsh" emerged as a concise, clear naming convention that pairs neatly with its fragment counterparts.

Because this is all convention-based, you’ll notice many stylistic differences where teams pick extensions according to shader stage, engine preference, or historical tooling needs, meaning two ".vsh" files might both represent vertex shaders yet contain totally different styles—GLSL syntax, HLSL syntax, or engine-preprocessed code—so ultimately ".vsh" simply aids clarity and tooling rather than serving as a strict standard.
