okay, that is called directory indexing. Automate??,,,no! [create a zip folder with all the content (a.zip), upload to /root and extract]
.htaccess file in the /root directory (public_html):
will send all directories 403:
https://www.ctyrd.org/assets/css/
.htaccess file in the /directory (/download/):
will allow directory and sub-directories to be indexed:
https://www.ctyrd.org/download/
The absence of a default index file in a directory will cause the server host to go 403, because the server defaults to "Option -Indexes". If you know the name of the file in directory that is not a default Index file name, HTTP request will be answered.
