title: How can I exclude folders in All-in-One WP Migration?
body: <p>I want to exclude the folder <code>/wp-content/uploads/download-manager-files</code> from backup because it contains files with several gigabytes of data.
  For this I used the following hook in the <code>functions.php</code> of my theme:</p>
  <pre class="lang-php prettyprint-override"><code>add_filter('ai1wm_exclude_content_from_export', function($exclude_filters) {
  
  $exclude_filters[] = 'uploads/download-manager-files';
  
  return $exclude_filters;
  });
  </code></pre>
  <p>The backup runs successfully, but it includes the <code>/wp-content/uploads/download-manager-files</code> folder.</p>
  <p>How do I apply the hook correctly to make it work?</p>
