That means you are trying to run WinSCP command[s] directly on Windows console (or in a batch file), instead of putting them to WinSCP script and running WinSCP from console/batch file.

You might be having this or similar problem:

Hi,

For example, here is a command to open a session:

First error:

"open" n'est pas reconnu en tant commande interne ou externe.

I think that is not a geed declaration.

See Automate file transfers (or synchronization) to FTP server or SFTP server

If you have tried something already and it does not work, please post your script and what problem you have with it.

Hi everyone,

I am a new user on WinSCP. I don't know how automate WinSCP tasks in order to retrieve a file in FTP. It seems there are three steps:

1. To log in;
   
2. To retrieve a file in FTP.
   
3. To log out.
   

Of course, there are several pages where it explains different WinSCP commands. I built different scripts, it doesn't work.
https://winscp.net/eng/docs/scripting#commands
https://winscp.net/eng/docs/scriptcommand_get#examples
Batch files often tell me get command or another doesn't exist.

For information, I am under Windows11.

Thank you for your help.
