[数值计算] 不支持32位以上的字符，批处理计算磁盘空间怎样以GB为单位？

怎么才能使导出的文件单位是G呢？ 不支持32位以上的字符，能不能曲线救国？通过其他办法解决一下

推荐试试PowerShell

CALL出来影响效率 直接FOR里计算吧

set md=1048576

       if exist %%i: (
          set num3_str=

          for /f "tokens=3" %%j in ('dir /-c %%i:') do set num1=%%j00
          set len=0
          set s=!num1!
          for %%j in (16 8 4 2 1) do if "!s:~%%j!" neq "" set/a len+=%%j&set "s=!s:~%%j!"
          set/a "r=!num1:~,8!%%md,m=!num1:~,8!/md"

要加setlocal enabledelayedexpansion
