JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
You can always see the total space used by your uploads when clicking on the little person figure in the top right:
Clicking on it will show how much you have used of your current limits.
However, there is not currently a way to see how much space each one of your forms is taking up. Deleting the submissions associated with your file uploads will free up more space though if you need it.
If you have any further questions, let us know and we will be happy to help.
