so i bought a dns 325 I am currently in the process of copying all my media to it. I am also a mas user.  My question is related to the dlink cloud.    I updated the firmware so the dlink would be available to me.  When i registered, it installed  some cloud folders folders in my volume 1.  Do I need these folders?  Should I install my media in these folders?
I don't understand why I need the dlink cloud since I can access the NAS from the internet?  I thought that a NAS is the same thing as a cloud. Please forgive my ignorance.
