It turns out that most operating systems do not have built in support for Blu-Ray DVD burning. For an operating system to allow you to drag-and-drop files onto a CD to burn them, the operating system must support burning Blu-Ray disks.
The only way to actually do that is to use third party software that adds drag-and-drop support for Blu-Ray disks to the operating system. Alternatively, you could use a program (such as Nero) to burn the files to a Blue-Ray DVD.
