XI remove last line feed (file adapter)

[Riser]

Dear expert,
We are using the file adapter in XI in order to create a txt file which is sent to an external ftp server. Every line ends with a line feed. I need to remove the last line feed after the last record, since the ftp server thinks that one more line is going to be sent (which is not the case).

Do you have any ideas / experiences in deleting the last line feed in the file adapter? Or workaround solutions?

All inputs are very appreciated!!
Thanks,
Riser
