At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed.

You can manage files on your form submissions page. To delete uploaded files, you have to delete each submission where the files are attached.
I would suggest to integrate your form to either of the following file services so files uploaded to your form will be forwarded to the following service. This would give you ease and convenient way of managing your form submission files.
Hope this helps!
