| The SCP protocol allows only file transfers in both directions. 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]]). For access to non-UNIX servers it is necessary that the server have at least a UNIX-like shell. | The SCP protocol allows only file transfers in both directions.

| - | ===== [[ftp]] FTP (File Transfer Protocol) ===== | ||
| - | FTP, being the oldest of the three, is most widespread transfer protocol of nowadays. In its basic form it inherently insecure, sending all data (including passwords) unencrypted. There is also secure variants ([[ftps|FTP over TLS/SSL]]). FTP is functionally inferior to SFTP. Also it is less platform independent than later versions of SFTP, mainly in respect to directory listing. | ||
