It's not possible (or hard to implement) in simple scripting.
Though, would it work, if you run synchronize second time against the other folder?

Or, you can use .NET assembly. Call Session.SynchronizeDirectories.
And then iterate returned SynchronizationResult.Uploads, uploading each synchronized file to the other folder.

See these articles that cover similar tasks:

Hi,
I have a script that connect to a ftp server and then synchronize the local folder with the remote folder, that works fine, then i need to that files synchronized(only new files) copy to another folder on the remote(ftp server)
This is the script to synchronize, small but efficient.

I have try move, but that move all the files not only the synchronized.

How can i do that? it there is a way.

Thanks
