How to download all the uploaded files at once as zip file form email notification?

Also, either with dropbox integration or without, is there a way to create a link in the email notification we receive to download all uploaded files at once as a zip file?

Unfortunately, it is not possible to create a download link zip file for all of the uploaded files in the submission via the email notification. All the files will have their own download link.

You could, however, download all the file uploads in the submissions page, it will give you a zip file there.

Thank you for understanding.
