Setting WinSCP with explicit TLS encryption

Question

I am trying to connect to a FTP server with following setting

This setting works well and I can connect to FTP server via GUI (version 5.7.5)

However, when I try to convert these settings to script

winscp.com /command "option batch abort" "option confirm off" "open ftp://username:password@ftp.example.com:21 -   
explicittls /" "put -filemask=>1D  D:\Backups\*.bak /" "exit"

and run it from cmd, there is an error message indicated that there is

Too many parameters for command 'open'."

What did I do wrong here and how to resolve it ?

Answer 1

It's

winscp.com /command "open ftp://username:password@ftp.example.com/ -explicit" ...

or simply

winscp.com /command "open ftpes://username:password@ftp.example.com/" 

See:

• https://winscp.net/eng/docs/scriptcommand_open
• https://winscp.net/eng/docs/session_url

You get the "Too many parameters for command 'open'" because of the / after the explicittls. Or because of the explicittls itself, if you really have the spaces there in-between the - and the explicittls.

You can use Generate Transfer Code Dialog to have WinSCP generate the script or batch file for you.

Side notes:

• option batch abort and option confirm off are not necessary since 5.7 anymore (they are implicit with /command);
• you do not need to specify port 21, it's the default port for FTP;

Answer 2

Try the following line:

winscp.com /command "option batch abort" "option confirm off" "open ftp://username:password@ftp.example.com:21 -   
explicittls" "put -filemask=>1D  D:\Backups\*.bak /" "exit"
