The Website Explorer lets you manage the pages and files of your website.
You can drag external files to it if you want them to be published to your website like files for users to download. However you can only drag files which are not HTML files created by the Website Realizer out of the explorer.
You can apply a template to a page opened in the Page Designer by dragging the template from the explorer and drop it to the page.
Please note that Undo and Redo actions are not supported in the Website Explorer. Files deleted are permanent and cannot be restored. If you delete a file which is linked to by other HTML files, a warning message will be displayed showing which pages are using this file. You should only delete it after making changes to the affected pages by removing the links or changing it to another file. This approach should be taken until no warning message is displayed. This way you can make sure that your site will not have links to missing files in the website. For external files, please use the "Check Http Links" function.
