I need a desktop exe to change the file extension of certain files from .htm to .php
Please see attached pdf for a diagram of how the files are arranged:-
I start off with ‘folder' Inside this are around 200 subfolders. Inside each of these are 4 files. I want to be able to rename the file named [url removed, login to view] to [url removed, login to view] in all of the 200 subfolders.
