How do we remove carriage return at end of file after FCC?

PI 7.4 - I've implemented a standard File Receiver FCC but I was wondering if there is a way to avoid the last carriage return at the of file after FCC? I tried several endSeparator like 'nl', '0x0A','0x0D' and '0' but it does not satisfy the requirement.

Sample:

1 Recordset LF

2 Recordset LF

---extra line--- How to remove this?
