    Outside of your DOS world, your header file is meaningless.

    If you are using GCC then you could just include the path to the headers like normal:
    in main.c:
    #include "header.h"

    Then when compiling:
    gcc main.c -I/FolderRoot/FolderZ/ -o myApp

    Or this can be set in the Makefile if you are using that. Typically hardcoding even relative paths into include statements is bad juju.
