Need your assistance with Windows cmd shell script - windows

Question

I have following script that removes all subdirectory from ROOT directory and removes all files in a ROOT directory except *.bat files.
pause
FOR /R C:\Temp\ %%F IN (*.*) DO IF NOT "%%~xF" == ".bat" DEL /F /S "%%F"
for /d %%i in ("c:\Temp\*") do rmdir /s /q "%%i"
pause
Help me improve script that it can also scan files *.bat in a ROOT subdirectories and remove all files with other extensions.

Test. If what it shows in console is what needs to be done, remove the echo command from destructive lines keeping the rmdir or del commands.
#echo off
setlocal enableextensions
set "root=c:\temp"
rem For the %root% tree
for /r "%root%" %%d in (.) do (
rem Test for the presence of .bat files under directory
dir /s /b "%%~fd\*.bat" 2>nul | find /v "" > nul
if errorlevel 1 (
rem If there is no .bat files under directory, remove directory
echo(**** rmdir /s /q "%%~fd"
) else (
rem There are bat files in directory or under it. Remove anything else in this directory
for %%f in ("%%~fd\*") do if not "%%~xf"==".bat" echo(-------- del "%%~ff"
)
)
EDITED - To adapt to comments - How to adapt the code so it will process more than one root folder? Take the code and convert it into a subroutine, then call it with the corresponding root. Iterate over the list of root directories
#echo off
setlocal enableextensions
for %%r in ("c:\temp" "c:\temp2" "c:\temp3") do call :processRoot %%r
endlocal
exit /b
:processRoot
setlocal enableextensions disabledelayedexpansion
set "root=%~1"
rem For the %root% tree
for /r "%root%" %%d in (.) do (
rem Test for the presence of .bat files under directory
dir /a /s /b "%%~fd\*.bat" 2>nul | find /v "" > nul
if errorlevel 1 (
rem If there is no .bat files under directory, remove directory
echo(**** rmdir /s /q "%%~fd"
) else (
rem There are bat files in directory or under it. Remove anything else in this directory
for %%f in ("%%~fd\*") do if not "%%~xf"==".bat" echo(-------- del "%%~ff"
)
)
endlocal
goto :eof
