The way i do it with Winscp, I use the gui part sense I download any per compiled files to my windows box and open the miner in a Winscp GUI window then go to what ever folder on the right side i need in the GUI and only use SSH when needed for CMD commands and also make sure if you use the GUI for Winscp right click the file, to give it full access after it's on the miner so you can use the file .  you can either drag it from windows or send it over from left to right in the GUI an can set it up to give full access as it's dragged from the windows box .

only time i really use SSH is with some command lines or compiling, some stuff you have to compile in Linux or it won't work by dragging it over . or doing updates that can only be done using SSH.

I do it something like this once I'm logged into SSH for the miner

use SCP for the file protocol set it to port 22, host is the antminers ip . user is root pw is admin if you right click the login on the left side it gives you the option to use SSH .. in the GUI it looks like two computers just above the new session button on the left middle section for SSH using the Winscp gui ..

cd /config

./set_voltage 1 c0
./set_voltage 2 d0
./set_voltage 3 d0
./set_voltage 4 b0


I would make a video how to but I suck at making videos.
