for /f "delims=" %%i in ('dir /b /a-d *.txt') do (
setlocal

(for /f "delims=" %%k in ('findstr /n .* "%%i"') do (
set "str=%%k"
setlocal enabledelayedexpansion
echo=!str:*:=!|findstr /i /b  "!z!" 1>nul && set aaa=1
if defined aaa (
echo=&echo=&echo=
echo=!str:*:=!
echo=&echo=&echo=
set aaa=
) else (
echo=!str:*:=!
)
endlocal
))>"new_%%i.txt"

endlocal
)
