Hello, @bnourse,
The File generator option is created to speed up the site performance and avoid calling the styles of elements that you don’t use on your site. Use this tool if you are an advanced user ( it may cause style issues on the frontend )
So please if you want to use this feature take a complete backup of your site first.
And yes, if you do not use Elementor Page builder on your site, then you can check yes all its options and features, it will remove all the CSS and JS including the particular feature from your site which loads your site fast…
Furthermore here is an article https://xstore.helpscoutdocs.com/article/100-how-to-speed-up-my-website .
I hope it helps.
