用于比较文件夹大小（以字节为单位）的批处理文件

Question

现在硬盘很大，我想把我所有的照片都放在上面，有时会检查我是否错误地添加或移动了任何文件。

这个是最接近我需要的那个，但我不知道它能给我显示所有文件夹，只显示我选择的文件夹

How to list all folder with size via batch file

我需要一个简单的批处理文件，它可以进行字节计数并将其与应该回显的数字进行比较，不管好坏，然后在我选择的文件夹上执行相同的例程。提前感谢您的帮助

set "folder=DVD-001 - 4,471,234,796" 

set "size=0

for /f "tokens=3,5" %%b in ('dir /-c /a /w /s "%%~fa\

@echo foldername  !size! Bytes

IF !size! EQU 4471234796 (@echo good) ELSE (@echo oops)

:next folder

set "folder=DVD-002 - 4,590,775,746"

set "size=0

for /f "tokens=3,5" %%b in ('dir /-c /a /w /s "%%~fa\

@echo foldername  !size! Bytes

IF !size! EQU 4590775746 (@echo good) ELSE (@echo oops)

与大小为的预定义文件夹列表相比：

@echo off
setlocal enableDelayedExpansion

for /f "delims=: tokens=1,2*" %%a in ('^
    echo DVD-001: 4471234796: f:\folder1 ^&
    echo DVD-002: 4590775746: d:\another folder ^&
    echo DVD-003: 1111111111: e:\folder 3 ^&
    echo DVD-004: 2222222222: c:\folder 4 ^
') do (
    set status=

    rem trim the path
    for /f "tokens=*" %%c in ("%%~c") do set folder=%%~c
    for /l %%c in (1,1,100) do if "!folder:~-1,1!"==" " set folder=!folder:~0,-1!
    for /l %%c in (1,1,100) do if "!folder:~-1,1!"=="\" set folder=!folder:~0,-1!

    rem trim dvd size
    for /f %%b in ("%%~b") do set dvdsize=%%~b

    rem get folder size
    set size=
    if exist "!folder!" (
        rem save penultimate line
        for /f "tokens=2,3*" %%s in ('dir "!folder!" /s /w /a 2^>^&1') do (
            set prev=!cur! & set cur=%%t
        )
        rem combine digit groups
        for /l %%s in (0,1,20) do (
            if "!prev:~%%s,1!" geq "0" if "!prev:~%%s,1!" leq "9" (
                set size=!size!!prev:~%%s,1!
            )
        )
    ) else (
        set size=NOT FOUND
    )
    if !size!==!dvdsize! (
        echo GOOD %%a: !dvdsize! == !folder!
    ) else (
        if "!size!"=="" set size=ERROR
        echo OOPS %%a: !dvdsize! ^<^> !size! !folder!
    )
)
pause

在两个文件夹都存在的情况下，仅列表模式下的双向 robocopy 会更可靠：

@echo off
set DIR1=d:\somefolder (no trailing slash!)
set DIR2=e:\anotherfolder (no trailing slash!)
robocopy /L /njh /njs /ndl /s "%DIR1%" "%DIR2%" | find "%DIR1%"
if errorlevel 1 (
    robocopy /L /njh /njs /ndl /s "%DIR2%" "%DIR1%" | find "%DIR2%"
    if errorlevel 1 (echo GOOD & goto DONE)
)
echo OOPS
:DONE
pause

它也会列出不同的文件。
