WordPress installed in a sub folder now I can't move it

Hi all

I’m building a site for a friend. The web address is

https://www.awts.net.au

I installed wordpress here
https://www.awts.net.au/wordpress

So I could develop the site without disturbing the main site.

And now want to move it to the root folder.
I tried doing this and the index page worked but I can’t link to any other pages as the links remain
https://awts.net.au/wordpress/index.php/faqs/
(not sure why they’re saving in index.php either.

Also once moved the wp-admin doesn’t work either cos it’s in a folder called wordpress/wp-admin

Any help would be much appreciated.

Thansk
