A .VSH file is widely implemented as a vertex shader file containing GPU-run code that transforms vertex positions with model/view/projection matrices and passes along attributes including mapping sets, normals, and colors for later shading, but because `.vsh` isn’t bound to one universal definition, certain engines may also use it for custom shader representations.
The most direct way to verify the nature of your .VSH file is to inspect the context surrounding it, starting with opening it in a text editor to spot GLSL markers like `mat4` or `gl_Position`, or HLSL patterns such as `float4x4` with semantics including `TEXCOORD`, while also reviewing whether it appears in shader-centric folders—like `materials`—and checking for companion files or project references that explicitly load or compile it as part of a vertex/fragment shader pair.
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 functions mainly as a visual cue, where its “v” for vertex and “sh” for shader inform you that it contains vertex-shader code, and when combined with a partner extension like .fsh for fragment shaders, it clearly signals how files line up within the rendering pipeline.

Another reason “.vsh” is used relates to how shaders must be processed separately 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 .vert/.frag, and “.vsh” emerged as a concise, clear naming convention that pairs neatly with its fragment counterparts.
Because it’s convention-driven, you’ll also see plenty of differences in how teams use shader extensions, with some choosing names based on shader stage, others following engine traditions, and some keeping older extensions for legacy or tooling reasons, which explains why two “.vsh” files from different projects may both be vertex shaders yet look entirely different—one GLSL-like, another HLSL-like, and another full of engine-specific macros—so in the end “.vsh” isn’t a universal rule but a practical naming choice that helps both humans and build tools organize and process graphics assets correctly.
