FTP相关网络协议

WinSCP 上的解释非常简单到位，喜欢

How do I make WinSCP show localized and/or UTF-8 encoded (Unicode) filenames correctly?

FTPS

FTPS (also known as FTP Secure and FTP-SSL) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols.

SFTP (SSH File Transfer Protocol)

Despite SSH in its name, it is designed to work over any reliable data stream, but WinSCP supports only operation over SSH, which is also by far its most common usage.

Unlike SCP, for connection with an SFTP server you do not need access to shell (although some implementations may still require that).

SCP (Secure Copy Protocol)

SCP is mostly used with SSH-1. SCP is an older protocol but almost universally supported on Unix-like platforms as part of an SSH protocol suite. It is rarely supported on other platforms. SCP is a descendant of the ancient “rcp.”
