WebDAV duplicate without temporary local copy

Hi.

I am working on a c# application using WinSCP library.
I try to duplicate a remote file but this operation returns an exception 400 Bad request.

Using WinSCP application i can duplicate only with a temporary local copy. So, duplicate with WebDAV without temporary copy is impossible?

I assume you get the same error as in code?

It is possible. But your server seems not to support it.

Yes, error code was the same.
I think that server not support duplication. Thank you.
