.PCH File

The pch file extension is associated with Microsoft Visual C++. The pch files are used for Visual C++ pre-compiled header files.

In computer programming, particularly in the C and C++ programming languages, a header file or include file is a file, usually in the form of source code, that is automatically included in another source file by the compiler.

Typically, header files are included via compiler directives at the beginning (or head) of the other source file.

A pch file extension is related to the Microsoft Visual Studio and Visual C++ development environments. A pch file stores pre-compiled header.
