drupal - How to add additional fields to a file field/widget in Drupal7 -

I have a file field in Drupal 7 that I need to add additional fields.

Currently only available field file uploads and there is a description. I'd like to add a dropdown with a title field and some hard-code options. I still need all the functionality of the file field.

How can I do this? I think I need to create a new file widget but it is not sure how to get started.

Thank you.
