Transfer DNG from Mavic to tablet through Wifi?

[Steinsvik]

Hi
Is it possible, using some sort of file browser or similar, to transfer DNG raw files from the Mavics microSD card to my Android tablet, using the direct Wifi connection?
The DJI Go4 app only seems to read jpegs, not DNG.

If only dji allowed connecting the usb cable to copy data from mp to pc without turning on that would be perfect!
