A .VSH file is often used to store vertex shader code that the GPU executes to transform vertices into final screen space using model/world/view/projection matrices and to pass forward helpful information like UV inputs, normals, and colors, but since `.vsh` isn’t a formal universal standard, some projects may adopt it for non-shader content.
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 `float4x4` 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 doesn’t resemble readable code and instead shows unintelligible characters or blank squares when opened in a text editor, it may be a binary asset such as a compiled shader blob or an encrypted/compressed file that only the engine’s tools can interpret, so the best approach is to use the extension as a clue but confirm by checking the file’s raw content, the nearby folders and companion files, and any project references that load it, since those three checks usually reveal what a `.VSH` file actually is.

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 the “.vsh” extension persists comes from automated shader processing, where asset pipelines or mod loaders depend on extensions to locate and compile shader files, and using a dedicated suffix avoids confusion with normal code; different environments settled on variants like .fx/.shader, and “.vsh” fit well as a simple naming scheme that clearly marks vertex shaders.
Because everything depends on conventions rather than strict rules, teams frequently adopt different naming approaches tied to shader stage, engine requirements, or old tooling constraints, which leads to two “.vsh” files being vertex shaders but looking nothing alike—one GLSL-based, another HLSL-based, another heavily macro-processed—so “.vsh” mainly supports organization and build pipelines instead of representing a universal standard.
