A .VSH file usually represents a vertex shader used by the GPU to help draw 3D scenes, handling vertex transformations through model, view, and projection matrices and forwarding details like texture coordinates, normals, or colors to the fragment shader, but because `.vsh` isn’t a strict global standard, some engines may instead use it for custom shader text.

The fastest way to figure out what your .VSH file actually is comes from inspecting the context around it, especially opening it in a text editor to see if it includes GLSL cues like `uniform` or `gl_Position`, or HLSL cues such as `mul(...)` and semantics like `SV_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 opening the file reveals random junk characters rather than normal text, it’s likely a binary item—possibly a compiled shader or an encrypted/compressed engine asset—meaning you’ll need the engine or its tools to interpret it, and the most reliable method is to treat the `.VSH` extension as a hint while verifying by inspecting its contents, reviewing its folder neighbors, and locating project references that load it, which together normally clarify its real purpose.

The ".vsh" extension exists mostly as a naming shortcut 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" became common is that shader pipelines depend on extension-based detection, allowing automated tools to compile and package shaders separately from normal files; over time communities adopted suffixes like .fx/.shader, and ".vsh" naturally settled in as a short, descriptive label that works well in paired naming schemes.

Because the choice is convention-driven, teams naturally settle on their own naming workflows based on stage type, engine expectations, or historical compatibility, meaning two vertex shaders both labeled ".vsh" can differ drastically—GLSL in one project, HLSL in another, or engine-modified code in a third—so the extension’s role is simply to help humans and tools keep shader assets recognizable and properly handled.
