Access External hard drive (on MK808) by Windows 7

Hi,I've installed Airdroid on my mini android TV - MK808.
The deviced is connected to external 500 Gb Hard drive by USB.


The HD path is :
mnt/usb_storage/USB_DISK0/udisk0/
I can access this folder by Airdoid, but it appear as empty.


How can I see the files there ?
Regards,
Kokofiko

Would you please open AirDroid on your device > go to "Tools" > "Files" and check if you could see the files in the folder?
