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.
Do you mean to upload the already received submissions and uploaded files to DropBox? Unfortunately, it is not possible to push the old submissions to DropBox with the integration. Only new submissions received after integrating DropBox will be sent to DropBox.
If you want to download all the attachments received on your submissions, you may consider downloading them at once from the Submissions view in order to upload it to DropBox manually.
Hope this information helps! If you are referring to something different or need any further assistance, please let us know. We will be happy to assist.
