A .VSH file is often used as a vertex shader file containing GPU-run code that transforms vertex positions with model/view/projection matrices and passes along attributes including UVs, normals, and colors for later shading, but because `.vsh` isn’t bound to one universal definition, certain engines may also use it for their own binary data.

The easiest way to determine what your .VSH file actually does is to check the evidence around it, beginning with opening it in a text editor to see whether GLSL-style features such as `uniform` and `gl_Position` appear, or if HLSL-type cues like `mul(...)` and semantics such as `SV_Position` show up, and then looking at its folder placement—especially shader-related directories—and searching project code for references that explicitly load or tag it as a vertex shader.

If the file opens as indecipherable characters rather than readable text, it’s likely a binary form—maybe a compiled shader or a compressed/encrypted engine asset—and in such cases only the engine or toolchain can interpret it, so the reliable method is to combine the extension hint with checking the actual content, the folder context, and the project’s load references, which usually confirms the `.VSH` file’s actual role.

The ".vsh" extension is used because it’s intuitive, not due to any formal specification, letting developers see immediately that it’s a vertex-shader file through the "v" + "sh" pattern, and making logical pairs like .vsh and .fsh stand out as corresponding vertex and fragment shader stages.

Another reason for using ".vsh" comes from the need for automatic shader handling, since tools and engines often filter by extension to compile or package shaders, and giving them a unique suffix keeps them from blending with regular code; as ecosystems matured with conventions like .vs/.

Because naming is convention-driven, developers often apply different extension patterns depending on shader stage, engine lineage, or legacy toolchains, so two separate ".vsh" files can both be vertex shaders but use distinct languages or formats—GLSL, HLSL, or engine-modified variants—meaning ".vsh" helps identify and process shaders but doesn’t impose universal rules.
