Question: what is psftp in putty?
Answer: PSFTP, the PuTTY SFTP client, is a tool for transferring files securely between computers using an SSH connection. ... PSFTP uses the new SFTP protocol, which is a feature of SSH-2 only. (PSCP will also use this protocol if it can, but there is an SSH-1 equivalent it can fall back to if it cannot.)
