Batch Script to get Disk Usage of Folders Recursively

Rob van der Woude has a nice batch script to get disk usage of folders & subfolders in Windows since there isn’t a built-in function.  This could be similar to Linux du command.

ECHO DiskUse, Version 5.01 for Windows 2000 / XP
ECHO Display disk space used by subdirectories (tab delimited)
ECHO.
ECHO Usage:  DISKUSE  [ startdir ]  [ /L ]
ECHO.
ECHO Where:  "startdir"  is the directory containing subdirectories to be
ECHO                     inventoried (default is the current directory)
ECHO         "/L"        is used for large numbers, over 2GB, to prevent return
ECHO                     of negative numbers due to batch math limitations
ECHO                     (integer division by 1000000 instead of properly
ECHO                     rounded mathematical division by 1048576)
ECHO.
