If you are a Linux user and new to SCP and want to use GUI based tool, you can use FileZilla. In Linux, you can also use the scpcommand on terminal to use SCP.

Meaning that you can use them to easily transfer files from local computer to remote server effortlessly using the drag and drop feature that is commonly offered by a GUI based FTP client.

Some FTP clients like WinSCP and Cyberduck already support SCP protocol. SCP is based on the Secure Shell (SSH) protocol. It is a network protocol that is designed specifically to transfer files from local computer to remove server or between hosts on a network. SCP (secure copy protocol) itself is quite similar to FTP. At the time of writing, FileZilla doesn’t specifically support SCP, but you can also use it as an SCP client with a little modification. Instead, it is an FTP client that allows you to transfer files from local computer to remote server or vice versa effortlessly thanks to its drag and drop feature.

FileZilla is not designed to be an SCP client.
