However, if you are talking about just URL’s that point to the ‘folders’ then that is something completely different. URL’s are controlled with the DNS settings. So, I am not sure which you are referring to. My guess is you have links within your html that you don’t want to have to change?????

I have the folder “mysubfolder2” with some PDFs in my prior non-Worpress site on https://www.mydomain.com/myfolder1/mysubfolder2/myfile.pdf. Now I want to change my site to WordPress and want to add the folder “mysubfolder2” to the WordPress site. This folder should be htaccess protected and the files should be accessed with the same URL (www.mydomain.com/myfolder1/mysubfolder2/myfile.pdf).

How could I achieve this?

Please, how can I achieve this:
