File overwrite working when I do not want to to.

Hello,

I'd like to push a file to a remote directory, however, I would like to not overwrite the file if it exists. According to the documentation, when batch mode is set to ON any choice prompt is automatically replied negatively. When option confirm is ON it should toggle confirmation of an overwrite. Neither seem to work with my script below. When the file exists, it continues to overwrite without error. What am I missing?

Script:

For me it works the way you want.
Do overwrite confirmations work for you in WinSCP GUI against the same server?

No, it does not confirm the overwrite on the GUI either. Could it be a permissions issue on my end or their end?

A verbose (log level Debug 1) can show more, if you want us to investigate. But I'm positive that it's a bug in the SFTP server.
