Your code can not work well on windows.
I find the error in your code:

        if os.name == "nt":
            combined_path = combined_path.replace("/", "\\")

should be

        if os.name == "nt":
            combined_path = combined_path.replace("\\", "/")

After this modification, it can work well.
