SCP is an older protocol but almost , 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 servers it is necessary that the server have at least a UNIX-like shell: one like that which is available with [[&opensshwin|OpenSSH for Windows]], for example. | + | 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". |

WinSCP is able to offer other features, implemented 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]]).

| + | SFTP is mostly operated as subsystem of SSH-2. SFTP is a | ||
| + | newer and more modern protocol, designed to perform in a manner similar to FTP. It is widely supported, even on non-Unix-like platforms, but not nearly as universally as SCP. Do not confuse SFTP (based on SSH) with FTPS/Secure FTP (based on SSL); they are distinct protocols which do not interoperate. | ||
| + | |||
| + | WinSCP supports SFTP version 0 (since 3.4), version 1 (since 3.4), version 2 (since 3.1), [[&sftp3|version 3]] (since 3.0 beta), [[&sftp4|version 4]] (since 3.2) and [[&sftp5|version 5]] (since 3.6.7). Support for version 5 is experimental as no server supporting the version is known and it currently does not bring any new functionality. | ||
| + | |||
| + | Unlike SCP, for connection with an SFTP server you do not need access to shell. Thus it is more independent of the remote operating system. | ||
