Howto delete file from FTP-Endpoint direct

Hi,

How I can send direct a file operation to the File-/FTP-Endpoint?
How I can delete Files over FileEndpointProducer?

I can create/change Files easy.

I not find a Way to delete only a created Files.

Inside my Example is the last Route, but can not delete the "fromJetty.txt"
File.

Best Regards
Eddi
