windws 下统计指定目标路径下各文件夹的大小

win_dush.bat

@echo off

IF [%1]==[] GOTO USAGE

if NOT exist "%1" (ECHO "%1" path not exist & GOTO END)

:DIR_PATH

dir /ad /b %1 > 1.txt

setlocal enabledelayedexpansion

for /f "tokens=*" %%i in (1.txt) do (
rem    echo 
    dir /s  "%1\%%i" |findstr 个文件 > 2.txt || echo. > 2.txt

rem    for /f "eol=0 tokens=1,3 " %%j in (2.txt) do set ll=%%k 字节 %1\%%i  %%j 个文件 
    for /f "eol=0 tokens=1,3 " %%j in (2.txt) do set ll=%%k & set ll=!ll:~0,-9! M %1\%%i  %%j 个文件 

    echo  !ll!  
rem    echo.
)

set total= 
Endlocal
del 1.txt 2.txt
GOTO END


:USAGE
echo Usage: %0 dir_path
GOTO   END 

:END
rem pause
