Batch file 无效号码。数字的精度限制为32位

在网上找到这个脚本。这是我下载它的基本原因。但我想知道几件事：

当脚本试图将字节划分为KB、MG和GB时，会出现错误 无效号码。数字的精度限制为32位

文件和目录的总数缺少右括号

提前感谢您的帮助。

数字精度限制为32位。 这是

set/a

的限制

有关变通方法，请参阅下面的“变通方法：32位”

算术表达式（集合/a）

所有数字都必须在32位有符号整数的范围内 数字（-2147483648到2147483647）以处理较大的 数字使用PowerShell或VBScript

解决方法：32位 32位限制的解决方法包括：

通过截断最后（3）个数字除以1000（或10的任意幂）

将数字拆分为单独的十进制数字，并“手动”执行所有数学和进位逻辑

其他脚本语言

解决方案#1可用于增加磁盘空间：

诀窍是将每个（大）数字视为字符串，然后 最右边的6个字符（数字）被截断，只有在 结果被视为一个数字

这是一个相当粗糙的解决方法，因为它在之前“四舍五入”了所有数字 做数学题

将每个子目录（%Count%/2）的半MB添加到%Total% 但是，它补偿了截断，所以总计是 比单个数字更准确

请注意，这些数字并不代表“实际”兆字节（1024 x 1024） 但是它相当于一百万字节（1000 x 1000）

Brian Williams的批次完美地演示了解决方案2 档案：

其他脚本语言的变通方法#3是不言自明的

进一步阅读

• -对于所有与Windows命令行相关的内容都是一个很好的参考

• -显示、设置或删除CMD环境变量。使用SET所做的更改将仅在当前CMD会话期间保留

如果您需要一个简单的磁盘空间欺骗，您可以通过将字符串子集并除以近似值来进行更粗略的计算。像这样：

@set /A ingb=%sizeout:~0,-7% / (1074)

其中%sizeout:~0，-7%子字符串sizeout，这是一种粗略的除以1.000.000的方法，无需处理任何舍入问题， 其中1074计算为1024*1024*1024/1.000.000
对于您需要的所有大小（KB和MB），也会执行相同的操作
MB:

%sizeout:~0，-4%/1049

KB:

%sizeout:~0，-4%

当然，测量单位越低，数字就越不准确，但对于GB来说，我用它来监控机器上的磁盘空间是非常准确的

我意识到所有这些都可以从DavidPostill的答案中扣除，但我只想提供一个适用于这种特定情况的复制粘贴示例。
以及更好的解决方案
对于大小不超过几GB的设备，精确到mb的精度
阅读代码中的备注，以便更好地理解

下面将获得gig中的总物理内存

@echo off
Rem This will produce a file for total ram
    Wmic Computersystem get totalphysicalmemory > c:\temp\trash\allram1.txt
Rem This will produce a clean text file with true value
     type c:\temp\trash\allram1.txt > c:\temp\trash\allram3.txt
REm  The following will skip a line (header)
    (    for /F usebackq^ skip^=1^ delims^=^ eol^= %%L in ("c:\temp\trash\allram3.txt") do echo(%%L) > "c:\temp\trash\allram4.txt"

Rem following will produce a clean file with actual number
    setlocal enabledelayedexpansion 
    set /p val=<c:\temp\trash\allram4.txt
    set newval=!val:~10,1!

rem it will find the new value wheter it is more than 10 gig
    echo !newval!   > c:\temp\trash\allram2.txt
rem This will determine if more than 10 gig is found (less than 10 gig) (more than 10 gig)
 findstr "off" c:\temp\trash\allram2.txt && (set  newval2=!val:~0,1!.!val:~1,1!) || (set newval2= !val:~0,2!)

rem if it is less than 10 gig it will have decimal for example 8.2gig or 17gig (if it is more 10 gig) 
echo !newval2!gig

@echo关闭
Rem这将为总ram生成一个文件
Wmic Computersystem get totalphysicalmemory>c:\temp\trash\allram1.txt
Rem这将生成一个具有真值的干净文本文件
键入c:\temp\trash\allram1.txt>c:\temp\trash\allram3.txt
REm以下内容将跳过一行（标题）
（对于/F usebackq^skip^=1^delims^=^eol^=%%L在（“c:\temp\trash\allram3.txt”）中执行echo（%%L）>“c:\temp\trash\allram4.txt”
Rem following将生成一个带有实际编号的干净文件
setlocal enabledelayedexpansion
set/p val=c:\temp\trash\allram2.txt
rem这将确定是否发现超过10千兆（小于10千兆）（大于10千兆）
findstr“off”c:\temp\trash\allram2.txt&&（set newval2=！val:~0,1！。！val:~1,1！）|（set newval2=！val:~0,2！）
rem如果小于10 gig，它将具有十进制，例如8.2gig或17gig（如果大于10 gig）
echo！newval2！gig

任何超过大约3Gb的文件大小都将超过32位整数大小。@Granity-实际上限制为2Gb。缺少文件和文件夹总数的结束符，因为代码只是删除它们；因此您需要手动附加它们。。。
