Display directory sizes/usage.

Syntax
      DIRUSE [options] Folders...

Options

   /K  Display in Kb
   /B  Display in bytes (default)
   /,  Use thousand separator when displaying sizes. 
   /Q:#  Quota limit, mark folders that exceed the size (#) with a "!".
         set %errorlevel% to ONE if any folders are found that
         exceed the specified size

   /*  Report on one level of subfolders (top-level folders)

   /D  Display only folders that exceed specified sizes.
   /S  Include detail of every subfolder in the output
   /O  Don’t check subfolders for quota overflow.
   /V  Display progress report for every subfolder

This utility does still work under Windows 10, although, like all Resource Kit tools, it is unsupported.
