The following is a list of project milestones. See also version history.
I started the first work on the project in about March 2000, while I was working in the IT department of University of Economics in Prague. The temporary name “WinSCP” (Windows Secure CoPy) was chosen until a nicer name was thought of (which never actually happened).
WinSCP was probably the first GUI file transfer client for SSH ever (at least on Microsoft Windows platform).
Original idea came from Jan Havlicek. In fact he wanted the tool a great deal. And he bothered me for weeks until I finally decided to implement it for him, without actually needing it myself beforehand. He was also the first one who spread the word about WinSCP on the Internet, before the project pages were set up.
During late 2000 distribution of the first releases of WinSCP 1.0 was started. The first WinSCP site was set up in October 2000 with the address
winscp.vse.cz. It was designed by Katerina Sramkova.
Version 1.0 supported the SCP protocol over SSH-1 only. There were several publicly available builds of the 1.0 release. Beside this there was never another release of the 1.x series.
In addition to the English version, there was also a Czech one. It made 1.0 the only localised version for years.
As version 1.0 was my first application of the kind, it was terribly designed, and consequently it was not worth extending. So eventually, after a break, when I decided to continue with the project, I needed to start from scratch. The results of my work were released in October 2001 as version 2.0 beta.
This version introduced SSH-2, public key authentication, alternative Explorer interface and many other features.
It took me more than one year before I felt 2.x series mature enough to release the first non-beta version, 2.2, in January 2003.
See original release announcement on cz.comp.linux (in Czech).
In June 2003 version 3.0 was released, introducing support for the alternative to SCP, the SFTP protocol. Over time it evolved from the alternative to the primary protocol. Despite this, the well-established name “WinSCP” was preserved.
After leaving the University, I have decided to move WinSCP project from the University server to SourceForge. The primary WinSCP site address was changed to
While WinSCP was in general an open-source project since its beginning, it was only with its migration to SourceForge that it turned into a true open-source by adopting the GPL license.
Since September 2003, WinSCP was also available as a plugin to the FAR file manager (discontinued).
Version 3.4 released in September 2003 was the first localized version since 1.0. There were Czech, Japanese, Russian and Spanish translations. Many other translations were introduced in later versions.
Thanks to Brandon Blackmoor WinSCP site got new design in December 2004.
After several unsuccessful attempts to find someone to write down some documentation for WinSCP, I have decided to go Wiki-way. With some help from the community, I finished it in May 2005.
In April 2007 version 4.0 was released, introducing support for the old insecure FTP protocol to finally cover all file transfer needs of WinSCP users.
After few years of preparations, WinSCP is also available as a plugin to the Altap Salamander file manager.
