Upload space is the available amount for you to store the uploaded files by you users. It is the same as the storage space.
For example, you have a form and it has a upload file tool on it where your users can upload photos. When the user submitted the form, the photos will be sent to our servers. If the image file size is 1mb, then 1mb storage space will be occupied on your available storage.
It is possible to limit the file size being uploaded to your form. Please refer to this guide if you want to more about it. Here the URL: http://www.jotform.com/help/33-Changing-the-Upload-Size-Limit
