Templates are used to present data in a pre-defined layout. Just like Joomla templates are used to determine the layout of a Joomla website by defining the module positions.
Note: Linking to Joomla articles is done in the native Joomla way using Menus and layouts (through com_content).
Form2Content creates default templates in order for users to immediately experience the working of F2C. Whenever a content type is created, F2C automatically generates a default template set (intro and main) and links to it.
As a result, when you submit your first article with F2C it will actually generate a Joomla article since there is a template present.
Remember: form content (data) + article template (layout) = Joomla article (html)
F2C Template location
The Form2Content templates are saved in:
< website root > /media/com_form2content/templates
