Folders with a specific name

Hi there. How are you all doing?

Need some help.
I have a list of chapters named 1, 2, 3… But the first chapter I want to be a Prologue. How can modify the compilation so next the prologue will be Chapter 1, Chapter 2, …


The first answer in this prior discussion may be of some help.

Thanks, AmberV. Useful as always.
