Transfer files between Multi controlled devices
Multi control makes copying files between devices familiar and simple.
Locate a file you’d like to copy. You can use the file browser on the device, like Windows Explorer, or My Files. Gallery is also supported on mobile devices.
Click and hold on the file, and drag it to the target device.
The file will be transferred into the Downloads folder on the target device.
Some apps also support files being dropped on them while they are open. For example, if you browse to a location in My Files, and then drop a file, the file will be placed in that folder.
