PSFTP, the PuTTY SFTP client, is a tool for transferring files securely between computers using an SSH connection.

PSFTP differs from PSCP in the following ways:

• PSCP should work on virtually every SSH server. 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.)
• PSFTP allows you to run an interactive file transfer session, much like the Windows ftp program. You can list the contents of directories, browse around the file system, issue multiple get and put commands, and eventually log out. By contrast, PSCP is designed to do a single file transfer operation and immediately terminate.
