I try to download a file on my documents folder but I come up with System.UnauthorizedAccessException. Please help

Maybe your application doesnt have permissions?

are you building a UWP app? if so, I would recommend you to change your save location from Documents library to any of Picture, Videos or Music and then check it in appmanifest capability

in Windows 10, (for security reason) any read/write task with the storage needs be achieved via system picker
