How do I get WinSCP to work with WinSSHD?
The latest WinSCP versions work fine in SFTP mode. Older WinSCP versions that only support SCP can also be made to work if you install the Cygwin bash shell and Cygwin’s SCP, configure the bash shell to be used in WinSSHD, and move WinSSHD’s scp.exe out of the way. However, it is much easier to simply use the latest version of WinSCP and toggle the setting to make it talk SFTP.
