It's computer to computer.You connect to the remote computer with a network screen name and passwords.In Windows there's like a wizard for this and YouTube also has some stuff.The problem is that the computer that you remote to does a screen log off.There is a short file out there that stops this log off.I see it as better than downloading or using a cloud or share sites.You just copy/paste to the remote computer.It's much faster than downloading and the file size seems to be unlimited.It looks like a VBox virtual when you're doing it.The remote computer appears in your desktop.You can actually control that computer remotely.
