Remove subfolder from WordPress URL using htaccess

Question

I've moved WordPress into it's own directory as per the instruction found on the WordPress support site.

I've got his working fine but the URL now shows http://www.example.com/subfolder/ but I want it to show without the /subfolder/

I can't seem to get the htaccess to remove the /subfolder/

Here's my current htaccess code

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www.)?mysite.com$
RewriteRule ^(/)?$ subfolder [L]

Answer 1

This should change http://www.mysite.com/subfolder/ to http://www.mysite.com/

RewriteEngine On
RewriteRule ^/subfolder/(.*)$ http://www.mysite.com/$1 [L,R=301]
