A .VSH file frequently serves 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 UV coordinates, normals, or color data downstream, though the extension can also appear in engines that reuse `.vsh` for project-specific structures.

The fastest way to figure out what your .VSH file actually is comes from looking at the context around it, especially opening it in a text editor to see if it includes GLSL cues like `vec4` or `gl_Position`, or HLSL cues such as `mul(...)` and semantics like `POSITION`, and then checking whether it resides in shader-related folders or sits beside partner files such as `.frag`, `.psh`, or `.ps`, as well as searching the project for code that explicitly loads or compiles it as a vertex shader.

If the file displays junk characters rather than readable source code, it might be a binary, possibly a compiled shader or a compressed/encrypted asset, and the safest method is to treat `.VSH` as only a hint and confirm by examining the actual data, exploring nearby directory context, and searching the project for load references, as these checks usually reveal what your `.VSH` file truly is.

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 ".vsh" is used exists because shader tools rely on it as engines and compilers scan for specific extensions to trigger shader compilation, and while shader languages are text, a unique suffix prevents mixing them with ordinary code; naming trends diverged into .vs/.ps, and ".vsh" became an appealing, compact option that pairs nicely with fragment-stage names.

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.
