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 UV data, normals, or colors to the fragment shader, but because `.vsh` isn’t a strict global standard, some engines may instead use it for proprietary compiled data.
The easiest way to determine what your .VSH file actually does is to check the evidence around it, beginning with opening it in a text editor to see whether GLSL-style features such as `vec3` and `gl_Position` appear, or if HLSL-type cues like `cbuffer` and semantics such as `POSITION` show up, and then looking at its folder placement—especially shader-related directories—and searching project code for references that explicitly load or tag it as a vertex shader.
If the file opens as garbled junk 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 `.

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 ".vsh" became common comes from engines applying rules by extension, allowing automated tools to compile and
package shaders separately from normal files; over time communities adopted suffixes like .vs/.ps, and ".vsh" naturally settled in as a short, descriptive label that works well in paired naming schemes.
Because the system relies on convention, not rules, teams often use varying extension schemes, 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.
