=== Nautilus connect to server by sftp ===
The Gnome file manager (AKA Nautilus) supports a multitude of server protocols, including ssh/sftp.
Allowing users to connect over FTP (especially SFTP) through the Gnome file manager is critical since a lot of Linux users rely on this protocol to access, download and upload files to servers and desktops running Linux over SSH.
Click on the “Other Locations” button to take the Nautilus and enter the server address: ''sftp:/ /lopeses.myqnapcloud.com:37132/''.
