I believe you are using the   echo Text  gt  gt  Example txt    function   If so the answer would be simply adding a      Dot  directly after the echo with nothing else there   Example   echo Blah echo Blah 2 echo   New line is added echo Next Blah

DISCLAIMER  The below solution does not preserve trailing tabs     If you know the exact number of lines in the text file  try the following method    ECHO OFF SET origfile original file SET tempfile temporary file SET insertbefore 4 SET totallines 200  lt  origfile   FOR  L   i IN  1 1  totallines   DO     SETLOCAL EnableDelayedExpansion   SET  P L    IF   i   insertbefore  ECHO    ECHO  L    ENDLOCAL       tempfile  COPY  Y  tempfile   origfile   NUL DEL  tempfile    The loop reads lines from the original file one by one and outputs them  The output is redirected to a temporary file  When a certain line is reached  an empty line is output before it   After finishing  the original file is deleted and the temporary one gets assigned the original name     UPDATE  If the number of lines is unknown beforehand  you can use the following method to obtain it   FOR  F   C IN   FIND  C  V      lt  origfile    DO SET totallines   C    This line simply replaces the SET totallines 200 line in the above script    The method has one tiny flaw  if the file ends with an empty line  the result will be the actual number of lines minus one  If you need a workaround  or just want to play safe   you can use the method described in this answer
