There are many directories inside d:\aaa on my computer, for example 111 222 333, and inside each directory there are many subdirectories and files. I want to calculate the sizes of these directories like 111 222 333. How should I write it?

@echo off&setlocal enabledelayedexpansion

for /f "delims=" %%a in ('dir /ad /b "d:\aaa"') do (

     for /f "delims=" %%i in ('dir /s /a-d/b "%%a\*.*"') do set /a n+=%%~zi

     echo total file size in %%a is !n! bytes

　 set "n=0"

)

pause>nul

Thank you very much, I learned quite a lot.

Why didn't I think of that? For a single directory, size is a whole.
For a large directory, then the sizes of the small directories inside can be calculated.
But could you modify it so the unit is KB, and put a comma every three digits?

@echo off&setlocal enabledelayedexpansion

for /r /d %%a in (*) do (

  for %%i in ("%%a\*.*") do set/a n+=%%~zi

  set/a kb=n/1024

  call :lp "%%a"

  echo.&set n=0

)

pause>nul&exit/b



:lp

if defined kb (

	set var=,!kb:~-3!

	set size=!var!!size!

               set kb=!kb:~,-3!

 	goto lp

)

set size=!size:~1!

echo about	!size!KB in %~1

set size=

Converted to KB.
