| - | Since version 3.0, WinSCP supports two secure transfer protocols, SFTP and SCP. Currently, many of the SSH servers support both protocols. Either of them have both advantages and disadvantages. This document contains their comparison to help you to decide which is most appropriate for your needs. The comparison lists either features that are characteristic to the specific protocol as-is, or features that are caused by the implementation of the protocol in WinSCP. | + | As of version 3.0, WinSCP supports two secure transfer protocols, SFTP and SCP.

| 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". | 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.

| - | Protocol itself allows only file transfers in both directions. Other features of WinSCP are realized using common shell commands, like ''cd'', ''ls'', ''pwd'', ''rm'', ''ln'', etc. For this, WinSCP, unlike command-line SCP clients, which allow only file transfers, requires full shell access and permission to execute other commands in addition to ''scp'' (see [[requirements]]). For access to non-UNIX operation system, it is necessary to have at least UNIX-like shell. One like that is for example available with [[&opensshwin|OpenSSH for Windows]]. | + | The SCP protocol allows only file transfers in both directions.
