OK after some tinkering and not forgetting to enable file sharing on the phone

i can send
files to the NAS over the home WIFI.
How to achieve the same results over data?
Having issues with installing Jdownloader on the NAS, Installed Java8 first then JD, run it and it opens
a browser window interface where i can see my download list. JD is running in a VM which basically
is like another computer.
I was expecting to be able to set a download and then switch off the PC and it continues on the NAS?
But it just seems to have changed the directory on my computers JD install and launched that instead.
Instead of C:/mydownload folder its now C:\mnt....
Maybe because JD is already running? Or have i done something wrong?
Thanks.
