Thank you for contacting Telerik Support.
doesn't provide such functionality to upload file directly to specific URLs.
After a file is selected for upload and a postback occurs on the server side you can access the uploaded file from UploadedFiles
property and manipulate it as you want.
Regarding the RadProgressArea, it will work fine(no additional code is necessary).
I hope this helps. I will be glad to assist you further.
