How to email someone a mix?

I'm away from home and have the Key61,an android tablet which accesses the Internet via the hotspot on my mobile phone. I have a USB-C cable for charging the tablet. Can I plug in the tablet via this cable ( it has USB -A connector on the other end) and see my Key 61's SSD, where my mix is saved?

Should work in controller mode. At least it works this way for an MPC One and its SD card.
