WS_FTP LE is a free commercial file transfer client for Windows desktops. The current edition is built on WS_FTP Home‘s code base and was reintroduced to the market in 2010.
WS_FTP LE offers a two-panel user interactive interface and its supported protocols are all variants of FTP/S.
WS_FTP LE is a stripped down version of WS_FTP Professional. The main features missing from the stripped down version are SFTP and scripting/scheduling.
The original version of WS_FTP LE was one of the most popular pieces of freeware ever (nearly a hundred million downloads). The original combination of WS_FTP LE and WS_FTP Professional provided one of the most successful implementations of the now-common “freemium” software business plan ever.
FULL DISCLOSURE: The president of File Transfer Consulting pushed through the retirement of WS_FTP Home and the return of WS_FTP LE while serving as VP of Product Management at Ipswitch.
