Access the file system of a Cerbo GX from Windows

Is there a way to access the file system of a Cerbo GX from Windows, similar to FTP or something like that?

I want to back up the entire Node-RED configuration and copy the entire /data/home/nodered/.node-red/ directory from Cerbo to a Windows computer.

Root access via ssh and putty, winscp

I got it working, I had accidentally used ftp instead of sftp. Now it works!

Why don’t you use the export function for all flows?

Because, that would be a backup of the flows only, but without the Node-RED configurarion files .config.*.json
