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.
Your account is over its limits since you are using 242.26 MB of storage space, while free accounts are allowed to have only up to 100 MB of upload / storage space. Current number of your submissions and used storage space can always be seen by clicking on the little person-shaped avatar at the top right corner of the screen.
You can see all account limits per plan on our pricing page: http://www.jotform.com/pricing
You will either have to delete the submission in which the file/files were uploaded, or you can upgrade to an account that allows more storage space.
Please let us know if you need any further clarifications or assistance, and we will be happy to help.
