What do I need to write in htaccess to change the main folder of the site?

Question

htaccess

there is a website script. I move it from the root folder of the site to the top folder. If you register my site / top / then the main page of the script opens, but all pages on the site give a 404 error due to the fact that the address of the pages does not change. That is, I follow the link and in the line it gives out my site / page, changing the top folder, who knows how to register this?
