This guide explains why there is a folder /icons/ within Infomaniak's Web Hostings.

Folder /icons/ on your Web Hosting

In some cases, a folder named /icons/ is present by default on your web hosting. This folder is usually accessible via HTTP, but is not visible in the FTP directory structure (www.domain.xyz/icons/).

This /icons/ directory is often used to store icons or specific images used to display directory lists. These icons are generally used by web servers to visually represent the different types of files in directories when they are viewed via a browser.
