How does space limit apply if we integrate file uploads to Dropbox or google drive?

I have created a form using starter/basic account. I have integrated the form responses/uploads with my dropbox. Does it still mean I only have 100 MB space (mentioned in the pricing page of Jotform) or do I have the overall space of my dropbox to receive uploads?

As the files will still be uploaded to the JotForm servers, uploaded files will count against the available upload space. 

If you have already integrated your form with Dropbox or Google Drive you may delete the submission in order to delete the file from the JotForm server, this way you will avoid to reach the available upload space  for your account. 

We have an app that will help you to automatically delete submissions as they are received, here is the link: https://apps.jotform.com/app/auto_delete_submissions

This way the submission will be sent to your integration and will be deleted from our servers, you will not be able to see it in the JotForm submissions page, but emails will work always and you can access to the submitted data send to your integration.
