Moving files from PC to 3D printer

Windows 11 on any Acer laptop
WinSCP 6.5.6
The printers ip is 192.168.5.115, port 80.
I know the password to SSH and get access to the root directory. When I ssh in this is what I get:
I then run a debug command to allow me to make changes to the files and add files. I just don't know how to configure WinSCP to do this.
Any help would be appreciated.

What does the "debug" do? Does it start a new shell with elevated privileges (like su does)? Or does it just somehow reconfigure the current shell/session?
In any case, you probably need to use SCP protocol and specify the "debug" as a shell:

But if it does not start a new shell, you might also need to follow it by start of the actual shell.
