WinSCP (Windows Secure copy) is an open source SFTP and FTP client for Microsoft Windows. Its main function is secure file transfer between a local and a remote computer. Beyond this, WinSCP offers basic file manager functionality. For secure transfers, it uses Secure Shell (SSH) and supports the legacy SCP protocol in addition to SFTP.
Development of WinSCP started around May 2000 and continues. Originally it was hosted by the University of Economics in Prague, where its author worked at the time. Since July 16, 2003 it is licensed under GPL and hosted on SourceForge.net.
