A .VSH file is most widely used for 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 custom text data.
To confirm what your .VSH file really is, the quickest method is to start by opening it in a text editor and look for shader-like syntax—GLSL hints like `varying` or `gl_Position`, or HLSL indicators such as `mul(...)` along with semantics like `POSITION`—and then study its folder placement, especially if it appears in directories such as `shaders` or alongside files like `.fsh` or `. If you have any kind of issues with regards to where as well as how to make use of

If opening the file reveals unreadable symbols 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 comes from convention rather than rule, giving developers and engine authors a quick visual indicator that the file contains vertex-shader code—thanks to "v" meaning vertex and "sh" meaning shader—which also pairs neatly with extensions like .fsh to reveal the vertex/fragment relationship in rendering.
Another reason ".vsh" exists is the need to treat shader files differently compared to normal source files, letting build tools or asset pipelines detect and compile them automatically based on extension, and although shader languages are plain text, a distinct suffix helps tools run the right compilation step and keeps developers from mixing shaders with general-purpose code; over time ecosystems adopted their own patterns—like .vs and .ps—and ".vsh" simply became one of the short, descriptive options many projects favored.
Because it’s convention-driven, you’ll also see different approaches 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.
