Combine two files using dos “copy” func

@echo off
echo ContentID = > package.conf
for /f "delims=" %%i in (package.conf) do set line1=%%i
for /f "delims=" %%i in (CID.txt) do set line2=%%i
echo %line1%%line2%>package.conf
echo Klicensee = 0x2A6AFBCF43D1579F7D738741A13BD42E>> package.conf
echo DRMType = Free>> package.conf
echo ContentType = minis>> package.conf
echo PackageVersion = 01.00>> package.conf

Output file:

ContentID = UP4306-NPUZ00210_00-MADBLOCKERALPHA1
Klicensee = 0x2A6AFBCF43D1579F7D738741A13BD42E
DRMType = Free
ContentType = minis
PackageVersion = 01.00
