父目录批处理

Question

在我之前的question中，Aacini向我提供了此代码：

@echo on
setlocal EnableDelayedExpansion

set "digits=8"
set mypath=%~dp0
cd /d "%~dp0"

rem delete old list from current even if read only
del /f list.txt

rem Assemble the factor with the proper number of digits
set "factor=1"
for /L %%i in (1,1,%digits%) do set "factor=!factor!0"

rem Accumulate size of all extensions in 2 groups of %digits% digits each
for %%a in (*.*) do (
   set "size=%factor%%%~Za"
   set /A "low[%%~Xa]+=1!size:~-%digits%!-factor, carry=low[%%~Xa]/factor, 
low[%%~Xa]%%=factor"
   set "size=%%~Za"
   set "size=!size:~0,-%digits%!"
   set /A "high[%%~Xa]+=carry+size"
)

rem Show results
for /F "tokens=2,3 delims=[.]=" %%a in ('set high[') do (
   if %%b neq 0 (
      set "low=%factor%!low[.%%a]!"
      echo %%a %%b!low:~-%digits%! bytes >>"%mypath%\list.txt"
   ) else (
      echo %%a !low[.%%a]! bytes >>"%mypath%\list.txt"
   )
)

现在我正在尝试在创建列表时搜索父目录。

我仍然希望将最终的测试文件保存到本地目录，所以没有更改！
