How can I free up some of the upload space?

If I have used too much upload space how do I get under the max allowed by my plan?

You need to delete the submissions that has the uploaded files to clear your storage space. Here's a guide: https://www.jotform.com/help/377-How-to-Delete-Form-Submission-Data.

You can monitor your current statistics in the Account Usage section. Here's the link: https://www.jotform.com/myaccount/usage.

Hope that helps. Thank you.
