title: Download files from url of site directory
body: <p>Two zip files and Two images are in <a href="https://example.com/directory" rel="nofollow noreferrer">https://example.com/directory</a>. (Since index.php file is available in this directory we don't know the file names of those files).</p>
  
  <p>Is there any possible way to find names of above four files using PHP or Linux commands?</p>
