Unload unused files CSS, JS

@baruch4552 those are files that are generated by WP Rocket and they are made of minified/combined JS files. Now, they will always contain unused JS as in some pages that code might be needed, while on some it might not be.

If you use Asset CleanUp to unload files that are not needed, then the final files generated by WP Rocket will be eventually smaller and the PageSpeed score will increase. It’s very tricky to chase every KB that is not used as it requires you to load alternative file versions (of the original ones) on pages where you want to achieve the highest score. This is usually done by developers who have time to spare and know well what they are doing.

Please check the following post: https://www.assetcleanup.com/docs/can-asset-cleanup-automatically-detect-which-css-js-files-are-needed-or-not-on-a-certain-page/ – it will give you some clues on how to detect unused files.
