I used to think SCP is a tool to copy files over SSH, and copying files over SSH is called SFTP, which is itself a synonym to FISH.
But now as I was looking for a Total Commander plugin to do this in Windows, I've noticed that on its page it says "Allows access to remote servers via secure FTP (FTP via SSH). Requires SSH2. This is NOT the same as SCP!".
If it's not the same then what am I misunderstanding?
