@BarryH_GEG could I tranfer lets say a film from Internal Storage to SDCard on KitKat??
Thanks in advance.
You can setup a two-window instance of My Files and drag-and-drop content directly from Dropbox to External SD.
You can also use Samsung Link to transfer files from another Samsung device, a PC, or a cloud service (Dropbox, OneDrive, Box) directly to external storage. IMHO, Samsung Link is one of the most overlooked features Samsung provides. It's fantastic for managing and viewing files across devices. For example, I can take a picture with my Gear which transfers it to my N3. I can view, edit, and share the pic from my N10.1-14 or PC seconds later. Anyway, here's a screen shot of it.
One of the great features of Samsung Link is that all registered devices are available to all other registered devices whether or not they're on the same Wi-Fi network. It even works over 3/4G. When devices are on the same network they have root access to each other. When they're not they have access to up to 10 user-specified folders or directories.
