Password Protection Question / Directories


This question came up before in another forum but I didn’t quite sewe the answer I was looking for, so here is a fresh go around:

I want to have a private members section of a website (subdirectory) where I want to restrict access only to members each with their own unique combination of email addresses and passwords.

In past software, I would create a folder (subdirectory) with the private section and place an .htaccess file in that folder.

I’m stuck in Blocs not knowing how to create a subdirectory how this can be done. While it’s probably a very simple process, I’m a bit lost being new to the program. Can someone explain, point me to a link or otherwise let me know if this is possible with Blocs?
