Moving WP to subdir and accessing root folders

Hello! I hope everyone’s doing well!

My WP site is installed in my root directory in the /public_html folder.

I saw that moving it into a subdirectory is very simple! 😊 And I would like to do so since the WP files tend to clutter things up quite a lot.

My question is the following: If I have other folders in the /public_html (root) folder, how will I be able to access them?

For example, if I put WP in a subdirectory such as the /public_html/wp folder, and decide to redirect my domain there (http://www.example.com will lead straight to /public_html/wp), then will I be able to access folders such as /public_html/gallery ? With what URL structure?

Thank you!
