A very important note to make is the naming convention of the default webpage for any folder.

The name index_html is reserved exclusively for the default web page within any folder. For example, to add a 'Landing Page' to a new folder, you would:

• Create a folder somewhere on the site
  
• Add a Web Page to that folder with the ID of index_html

Without the Web Page of index_html, the website will simply show the contents of the current folder the user is looking at. In some cases, this may be what you are looking for, such as a list of files for download, etc.
