    Hi @Alberto77,

    Welcome to Zyxel Community!

    It doesn't need to enter a specific dir.
    You may use get & put command to achieve the goal.

    Steps as follow:
    For standalone switch:
    1. Input get command to get config:

    2. Input put command to restore the config:

    Hope it helps,

    Hi @alberto77,

    Based on the screenshot, more likely the problem is more related to the application layer, as you could access the switch. I assume that the firewall inbound rule is blocking the FTP service.

    For a simple test, you may disable the PC firewall and wait for a bit and reconnect to switch via FTP. 
    Reminder: It might need a minute to reconnect again as the session needs to finish the traffic flow.

    After disabling the firewall, please try to "get config" again for verification.

    Tips: You may also add an allow inbound rule in the firewall settings if you don't want to disable the whole firewall application.

    Steps as figure below:






    7. Verification:

    Hope it helps.
