In tip 8300, I scripted DelMT.bat to delete empty sub-folders in a directory tree.

Jim Long scripted DelMT.bat, making use of the SORT /Reverse command and suppressing errors, resulting in a much simpler solution.

DelMT.bat contains:

@echo off
if \{%1\}==\{\} @echo Syntax DelMT Folder&goto :EOF
if not exist %1 @echo Syntax DelMT Folder - %1 not found.&goto :EOF
setlocal
set Folder=%1
:: REMOVE EMPTY SUBFOLDERS
for /f "tokens=*" %%A in ('dir /ad /s /b %Folder% ^|Sort /Reverse') do (
 RmDir "%%A" 2>NUL
)
:: REMOVE FOLDER, IF EMPTY
RmDir %Folder% 2>NUL
endlocal
