Overwrite existing files

Hello,
 
how can I tell the embedded FTP-Server to overwrite existing files. I always get errors like this:
 
176406 [pool-2-thread-3] INFO org.apache.ftpserver.listener.nio.FtpLoggingFilter - RECEIVED: RNTO status.txt
176421 [pool-2-thread-3] INFO org.apache.ftpserver.listener.nio.FtpLoggingFilter - SENT: 553 Can't rename file.
 
If I delete status.txt the transmission works one time. Then the file exists again and I get the same error message.
I can't change the programm that sends the files. Is there a way to allow the RNTO command to delete the existing
file before renaming?

mit freundlichen Grüssen / with kind regards

FtpServer does not have an option for this (Googling a bit on this
issue, seems like there is disagreement among FTP servers on how this
should be handled). You have some options on how to handle this:
* Simplest, write you own Ftplet that traps the RNTO and cleans out
existing files.
* Subclass our file implementation and replace the move() method with
one that allows existing files
