Can I use a different file upload manager instead of the default file upload?

Hello, I have a free account set up. I am using the Adobe Muse JotForm widget in a website I am designing. Can I use the JotForm form I create and use a different file upload manager instead of the JotForm file upload? Thank you for your help.

Unfortunately, you can't. Especially if you wish to get that different file upload into your form. We have a few file upload widgets that you can use. Please try them
