Can we receive an email about the submitted form with the uploaded forms?

3) make sure that I receive the forms in my emails after they click on submit ?

The short answer is Yes - yes you can.

All you need is to setup an email notifier as shown here: Setting Up Email Notifications

As soon as you do, you will receive an email when a submission is made, and if you do not remove it, the links to the uploaded files will be available as well.
