move ~xxx\* >nul
rd ~xxx
( for /f "delims=|" %%a in ('dir /a-d/b/on "*  Section 1*"') do (
    set "old=%%a"
    setlocal enableDelayedExpansion
    set "new=!old:  Section 1=!"
    rem ren "!old!" "!new!"
    echo !new!
    endlocal
) )>~tmp
set "n=1"
set /p n=start:
set /a skip=n-1
if %skip% gtr 0 (set "skip=skip=%skip%") else (set skip=)
