I’m not an expert at this though but from what I understood, I need to delete those old files.
Right, and upload the new ones instead.
But where do I place ‘files.zip’ and ‘patch.txt’?
‘files.zip’ just contains the same 3 files, but with directory structure preserved, so that might make easier to put the files on proper places.
‘patch.txt’ is provided for geeks, who might prefer using funny tools like ‘patch’ and ‘diff’ in Unix shell
