The Folder template is intended for displaying contents of a local folder, not a web page URL. If you have *folder in
Tools | Options | Browser | File extensions to display in internal browser view and set a Folder item's URL attribute to a local file path, the file content will be rendered in an Explorer view within UR.

The Document template is not intended to be created directly, but it used by UR when importing files. UR will assign additional attributes such as DocType, Document Size, Encoding, etc., when importing the file (these attributes are not user-creatable).

This is why it is hidden by default, although it can be shown via a registry setting.
