How can one structure a website so that only the folder is displayed in the navigation instead of the file itself?

To structure a website so that only the folder is displayed in the navigation instead of the file itself, you can use PHP to check if the current directory is a folder or a file. If it's a folder, you can display it in the navigation. If it's a file, you can skip displaying it. This can be achieved by using the PHP function is_dir() to determine if a given filename is a directory. 

$directory = 'path/to/your/directory';

$files = scandir($directory);

foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        if (is_dir($directory . '/' . $file)) {
            echo '<a href="' . $directory . '/' . $file . '">' . $file . '</a>';
        }
    }
}
