I am sorry, I am not abel to properly understand your question using translator. If you can describe more using English language, I will be more than glad to provide you more assistance.
As is now, the way I understand it is, -- you were asking if you can upload directly to Dropbox without the files being copied to JotForm anymore.
If I understand your question properly, I'd like to tell you that the files will always be copied to JotForm first before going to your dropbox account.
What you can do instead is delete the submissions with uploaded files after you have successfully uploaded already to Dropbox.
Just be careful in deleting submissions. Always make sure that a copy on your dropbox is already available.
Hope this help. Please contact us again anytime if you need further assistance.
