Batch splitting a .txt file

Hello,

I'm new to batch and I'm stuck on a problem: I have a .txt file containing an arbitrary number of lines (for example 135000) and I would like to split this file into x files with the same name +/- a number (to differentiate them) each containing 40,000 lines.
Is this doable in batch??

Thanks in advance

Best regards

    Here you go, you can do something like this: 
    @echo off setlocal enableDelayedExpansion set nbrLigneMax=4 Set nbrLigne=0 set nbrFile=0 for /f "delims=""" %%i in ('type "In.txt"') do ( if !nbrLigne!==%nbrLigneMax% set /a nbrFile=!nbrFile!+1& set nbrLigne=0 echo %%i>>File-!nbrFile!.txt set /a nbrLigne=!nbrLigne!+1 ) pause


    The file In.txt is the input file, the one you want to split.
    The variable nbrLigneMax is the number of lines you want per file.

    Here you go: 
    @echo off setlocal enableDelayedExpansion set nbrLigneEnteteMax=14 set nbrLigneEntete=0 for /f "delims=" %%i in ('type "In.txt"') do ( if !nbrLigneEntete! LSS %nbrLigneEnteteMax% echo %%i>>"EnTete.txt" set /a nbrLigneEntete+=1 ) set nbrLigneMax=4 Set nbrLigne=4 set nbrFile=0 for /f "delims=" %%i in ('type "In.txt"') do ( if !nbrLigne!==%nbrLigneMax% ( set /a nbrFile+=1 set nbrLigne=0 for /f "delims=" %%j in ('type "EnTete.txt"') do echo %%j>>"File-!nbrFile!.txt") echo %%i>>"File-!nbrFile!.txt" set /a nbrLigne+=1 ) del /f /s /q "EnTete.txt" > NUL pause

    Thank you, it works perfectly!
    I have another question:
    I need the batch to copy the header contained in the file In.txt into all the generated File-* files.

    P.S: This header is 14 lines long.

    Thanks in advance.
