title: How to add a project item to the repository with empty and not empty folders in Delphi 10.3.3
body: <p>I've created a project skeleton and added to the repository as a custom item. But when I want to create a project by the repository, it says:</p>
  <p><code>Could not copy file basefoldername\subfoldername1\filename1.pas</code></p>
  <p>I examined the radstudiorepository.xml and found a section like this</p>
  <pre><code>&lt;RADStudioObjectRepository Version=&quot;&quot;&gt;
    ...
    &lt;Items&gt;
      ...
      &lt;Item IDString=&quot;my repository item project name&quot;&gt;
        ...
        &lt;Files&gt;
          &lt;File&gt;basefoldername\subfoldername1\filename1.pas&lt;/File&gt;
          &lt;File&gt;basefoldername\subfoldername2\filename2.pas&lt;/File&gt;
          ...
        &lt;/Files&gt;
      &lt;/Item&gt;
      ...
    &lt;/Items&gt;
    ...
  &lt;/RADStudioObjectRepository&gt;
  </code></pre>
  <p>I haven't found a DTD or XSD for RADStudioObjectRepository on the net.
  Could you tell me how could I register a folder to create in this xml file?</p>
  <p>You can find the <code>radstudiorepository.xml</code> in this way:</p>
  <ul>
  <li>Select menu item <strong>File\New\Other</strong></li>
  <li>On the right pane of the <strong>New Items</strong> dialog <strong>RIGHT</strong> click on any item</li>
  <li>Select the <strong>Template libraries</strong> popup menu item</li>
  <li>In the <strong>Template libraries</strong> dialog you can see the value assigned to <strong>RAD Studio Object Repository</strong></li>
  </ul>
