A .VSH file commonly refers to 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.

To confirm what your .VSH file really is, the quickest method is to inspect it directly 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 `SV_Position`—and then study its folder placement, especially if it appears in directories such as `effects` or alongside files like `.fsh` or `.ps`, while also searching the project for any "vertex shader" or "load shader" references tied to its name.

If the file doesn’t resemble readable code and instead shows gibberish 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 ".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 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.
