File Extensions - I have a simple site without using perch navigation, just links in a header. Pages are currently using .html, I want to remove this extension

How do I do this please! ?

I currently have a htacess file with this:

<IfModule mod_rewrite.c> RewriteEngine on

Redirect to PHP if it exists.

e.g. example.com/foo will display the contents of example.com/foo.php

RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule ^(.+)$ $1.php [L,QSA]

</IfModule>
