If you want to disable FTP, you have to do it on the server side!
The intent was to have SCP and sftp enabled. That way usernames and passwords would not be sent n clear text. The source readme file indicates the parameters to pas to the compiler to accomplish this but I have been unable to locate a Borland C++ Builder 6 Pro or personal compiler.
What would that be good for?
Is there a possibility of posting a NON-FTP version of WinSCP on the download site? I have a need for such a version and have downloaded the source but can't seem to get a copy of Borland's C++ Builder 6 anywhere. I would be willing to make an appropriate donation to the project
