How can I upload the form answers(as .csv) to my FTP?

I need to update a csv file of all the answers each time one is submited. I know you can upload files, but what I want is the form itself.

Thanks in advance.

You may generate the CSV report with the submissions received on the form from the Submission view or from the reports section. Unfortunately, it is not possible to upload the CSV file to FTP automatically since the report can only be downloaded manually. 

Thanks!
