@echo off
set "dir1=C:\path\to\directory1"
set "dir2=C:\path\to\directory2"
set "dir3=C:\path\to\directory3"

if exist "%dir1%" (
    echo Deleting contents of %dir1%
    del /q "%dir1%\*"
) else (
    echo %dir1% does not exist
)

if exist "%dir2%" (
    echo Deleting contents of %dir2%
    del /q "%dir2%\*"
) else (
    echo %dir2% does not exist
)

if exist "%dir3%" (
    echo Deleting contents of %dir3%
    del /q "%dir3%\*"
