Dos - Delete the oldest file using DIR /OD and EXIT

The idea is to list all files by oldest date(DIR /OD) and then break out of the FOR loop on the 1st iteration using EXIT /B.

@ECHO OFF
SET FOLDER_PATH=%1
 
IF [%FOLDER_PATH%]==[] GOTO MISSING_ARGS
 
FOR /F "delims=" %%W IN ('dir /s/b/od %FOLDER_PATH%\*.rar') DO (
DEL /q %%W
EXIT /B 0
)
 
GOTO THE_END
:MISSING_ARGS
echo ERROR: FOLDER_PATH argument is missing! Supply FOLDER_PATH argument to the batch file.
 
:THE_END
@REM The end. Do nothing. There should be no other statement.
