How to create pages in wordpress template folder?

Question

HTML

Here in vp to create a page you need to create a page-name.php file in the root of the template and then you write this name in the admin panel in the shortcut.
And here is how to create pages in a folder, for example, so that the path is:
site-name.com/videos/index.php
site-name.com/videos/video1.php
site-name.com/videos/video2.php
and so on. ..

Answer 1

at the root you create videos/index.php

Answer 2

You can go the other way. I won't say that this is a good idea, but the method of implementation will do ....
You need such a url /videos/index.php, and not the fact that such a page exists in videos/index.php, etc.
Plugins are suitable for this:

https://wordpress.org/plugins/dot-php-pages/
You can also create WP pages without violating the WP "principles", from the admin panel and set them any url
