Hi @Baybtout
The ‘Loop File’ is not a file as such, but is a block of code which is used in any template to display 1 or more post object.
You can learn more about ‘the loop’ on the WordPress website.
Most likely, you want to find and edit the single.php or page.php file fo a single post. And the index.php or archive.php file for multiple posts pages.
That’s all I can help you with as this is support for ACF related questions, not basic core WP questions.
Thanks
