Batch file delete duplicates, nested once deep

Question

Yes, I did see: Delete duplicate files with Windows batch file

But I was unable to modify it to check each subfolder of that I specify, I have:

del "c:\...\Pictures\*\*-001.*"

But it doesn't like it. I only need to go one folder deep (each subfolder is a month) and I don't need to check the Pictures\ root.

I've tried this:

FOR %%F IN ("C:\...\Pictures\") DO FOR %%f IN ("C:\...\Pictures\%%F\*-001.JPG") del "%%f"

But that still isn't correct. Can anyone lend me a hand? I've very limited experience in batch files.

Set your real %startfolder% and look at the output. If it is good, remove echo before del:

@echo off &SETLOCAL
SET "startfolder=."

FOR /r "%startfolder%" %%i IN (*) DO call:doit "%%~i"
goto:eof

:doit
SET "fname=%~nx1"
SETLOCAL ENABLEDELAYEDEXPANSION
SET "fsize=!$%fname%!"
IF DEFINED $!fname! (
     ENDLOCAL
     IF "%fsize%"=="%~z1" ECHO DEL "%~1"
) ELSE (
     ENDLOCAL
     SET "$%~nx1=%~z1"
)
goto:eof

The code doesn't delete if filesizes are different.
