What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I believe you're looking to disable the uploaded file attachment from your form when a new submission is sent to you with the email notification.
Please refer to https://www.jotform.com/help/393-How-to-Attach-a-File-to-Autoresponder-Emails and you can then do the opposite to disable it for your email or autoresponder.
