delete older files who exist in another directory?

Question

I have two folders who have almost the same files and folders.

I want to consolidate them and delete all files in folderA that are the same in folderB (Same Date or Older)

Someone already asked Here about just deleting files without checking for date.

I want something similar but it should only delete if its the same age or older.

Thank You

try this:

@echo off&setlocal enabledelayedexpansion
pushd "%~dp0"


for /f %%i in ('dir /b a') do (call:CmpFTime LSS "a\%%~ni" "b\%%~ni"&&del "a\%%~ni")


:CmpFTime
SETLOCAL
set op=%~1
set fileL=%~2
set fileR=%~3
set attrL=%~4
set attrR=%~5
if "%op%"=="" set op===
if "%attrL%"=="" set attrL=/tw
if "%attrR%"=="" set attrR=%attrL%
for /f "tokens=1-6 delims=/: " %%a in ('"dir %attrL% /-c "%fileL%"|findstr "^^[0-1]""') do (
    set TL=%%c%%a%%b%%f%%d%%e
)
for /f "tokens=1-6 delims=/: " %%a in ('"dir %attrR% /-c "%fileR%"|findstr "^^[0-1]""') do (
    set TR=%%c%%a%%b%%f%%d%%e
)
if "%TL%" %op% "%TR%" (rem.) ELSE set=2>NUL
EXIT /b

if this contains any errors, feel free to comment, and i will do my best to fix them. i substituted a for foldera and b for folderb.
