Is Windows CMD FTP support SSL

I use command 'open' in cmd to open a conncection to my FTP site, and it requires SSL,
and the cmd replies

534-Policy requires SSL.
Win32 error:   Access is denied.
Error details: SSL policy requires SSL for control channel.

Is Windows CMD FTP support SSL, and how to enable SSL?

Re: Is Windows CMD FTP support SSL

I don't believe there is a native way to connect to an SFTP service.  You could, however, download Putty and use PSFTP from the command line to connect.  The command syntax is the same as FTP. 

You can download Putty here:

Re: Is Windows CMD FTP support SSL

Make sure you know what you're dealing with as well.

Is the endpoint SFTP (an SSH server) or FTPS (an FTP server encapsulating traffic with SSL)?  While the acronyms are only subtly different, they're entirely separate protocols.

It's usually FTPS on a Windows server, in my experience (and your error message seems to suggest the same).  This will somewhat dictate the client you can use.

From memory - Putty's PSFTP is an SFTP only client, FileZilla Client supports FTPS only and WinSCP supports both.  But don't quote me on that, as I've not been near any of them in a while and my memory could be hazy.
