@echo off&setlocal enabledelayedexpansion
set s=bBAathToHOMmEe
for /f "delims=" %%a in ('tree "\*\%s%"^|find ":\*\"') do set "t=%%~nxa"
rem 或者dir /L
set n=0
:lp
if "!s:~%n%,1!" neq "!t:~%n%,1!" (
    set /p=!s:~%n%,1!<nul
) else (
    set r=!r!!s:~%n%,1!
)
set /a n+=1
if "!s:~%n%!" neq "" goto :lp
echo;%r%
pause
