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 mapping info, normals, or colors to the fragment shader, but because `.vsh` isn’t a strict global standard, some engines may instead use it for engine-specific formats.
The fastest way to figure out what your .VSH file actually is starts with examining the context around it, especially opening it in a text editor to see if it includes GLSL cues like `attribute` or `gl_Position`, or HLSL cues such as `float4x4` and semantics like `TEXCOORD`, 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 a text editor shows garbled data or blank boxes instead of code, the file is probably binary, such as a compiled shader blob or a protected asset used by an engine, so identifying it depends on checking the extension as a clue, examining the binary signature, reviewing surrounding files, and finding where the project loads it, with these steps typically revealing what the `.VSH` file represents.
The “.vsh” extension doesn’t come from a mandatory standard, but rather from a simple naming habit developers use so they can spot shader roles at a glance, with “v” meaning vertex and “sh” meaning shader, which also makes pairs like .vsh and .fsh easy to link together as vertex and fragment shaders in the rendering flow.
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 .vert/.

Because the system relies on convention, not rules, teams often use their own naming logic, whether driven by shader stage, engine demands, or compatibility with older tools, which is why two “.vsh” files may share the same purpose but differ wildly inside, from GLSL-style text to HLSL-type structures or macro-heavy engine formats, making “.vsh” a convenient organizational choice rather than a mandatory standard.
