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.
This counter does not take into account the forms you create, it increases depending in the uploaded files in your forms, for example, you may have only one form in your account and allow there your users to upload files, then once this form has received 100 MB in the total uploads for all the submissions you will be notified and will need to either delete those submissions in order to get free space or upgrade your account.
We have just released a new feature that allows to download all your data at the same time, here is a link with more information about it as well as the steps to do it: New-Feature-Announcement-Export-Your-Data-in-Seconds-with-Data-Export
I would suggest you to integrate your form with a 3rd party app in order to keep your files and avoid to loose some data, here are the links where you will find the steps to integrate your forms with the most popular cloud services and send uploads to your FTP server as well:
Hope this helps.
