I need a Batch file that will merge / combine / append all the .CSV files in the current directory together with only one header row. The header row is the same in each file and is the first row of each file. I have tried the following: COPY *.CSV ALL.CSV and FOR %%1 in (*.CSV) do type %%1 >> ALL.CSV How can I add the first file as it is and then add all the others to it without the first row?

Try this: setlocal enabledelayedexpansion @echo off del all.csv set header=abcd ::change the content of header, above for %%a in (*.csv) do type "%%a">>all.tmp echo %header%>ALL.CSV for /f "tokens=1,* delims=" %%b in (all.tmp) do ( set x=%%b call :all2 ) del all.tmp goto :eof :all2 for /f "tokens=1,* delims=" %%c in ("!x!") do set y=%%c if !y!==!header! goto :eof echo !y! >> ALL.CSV goto :eof ------- Caution: any line identical to header will also be ignored.

Thank you much for your assistance. My initial testing shows that it works.
