寻找一个批处理脚本，该脚本允许从文件夹（.\source）获取文件并.rar在其他文件夹（.\target）上创建文件，并使用这些文件，但其中所有文件的最大大小是给定的.rar。
我已经存档、在文件夹之间移动文件和/或创建.rar包含所有源文件的文件。
问题是收集可变数量的文件以达到给定（输入选项）的聚合文件的最大大小。
找到了这个答案（分裂成.\folders，而不是.zip文件）回答@lo-ol：
@echo off & title <nul
setlocal enabledelayedexpansion
color 0a && cd /d "%~dp0" & title .\%~nx0
:next
set "_zOk=." && set _dir=<nul
set /a "_cnt+=1+0, _sz_lmt=209715200"
if not exist *.zip endlocal && goto=:EOF
for /f tokens^=* %%i in ('dir /b /o:s *.zip')do (
call :^) %%~zi 0000 "%%~fi" !_cnt! && echo\
2>nul cd /d "%~dp0!_dir!" && cd.. || mkdir "%~dp0!_dir!"
if not !_sz_lmt! gtr %%~zi move "%%~fi" "!_dir!\" >nul && echo\ Moved: "%%~fj" ".\!_dir!"
set /a "_sz_lmt-=%%~zi" && echo\Folder: "%~dp0!_dir!"
:loop
for /f tokens^=* %%j in ('dir /b /o:-s *.zip')do for /f %%K in ('
set /a !_sz_lmt!-%%~zj')do set "_szj=%%~K" && if not !_szj! leq -1 (
move "%%~fj" "!_dir!\" >nul && set /a "_sz_lmt=!_szj!" && echo\ Moved: "%%~fj" ".\!_dir!"
)
call %:^] "%~dp0!_dir!" && goto=:next
)
%:^)
set "_lst=%~1" && set "_dir=00%~4" || endlocal && goto=:EOF
set "_lst_=%~3!_lst!" && call set "_dir=Zip_!_dir:~-3!" & exit /b
%:^]
for /f tokens^=3 %%i in ('dir "%~1\*"^|findstr.exe ",.*bytes"
')do set "_zf=%%~i" && call set /a "_zf=!_zf:,=!/1024/1024" && (
cmd.exe /v:on /c "echo\Folder: "%~1\" Size: !_zf!MB" && exit /b )
但无法弄清楚如何将其反转为.zip文件。
EDIT2（修订澄清）：
有一个文件夹（.\source），其中有多个（假设有 100 个文件）.CSV 文件（source_file），大小可变，范围从（大约）500kb 到 +50Mb，带有一个“孪生”标志文件 - 尺寸较小（低于 100kb 左右），名称变化不大（source_file_flag）。
打算：
- 选择给定数量的文件（source_file + source_file_flag）以达到给定的总文件大小（Mb）- 当前可以选择给定数量（n）的文件
- 将 #1 中的“source_file”聚合到单个 .CSV 文件中，保存到 .\target 中，作为 pack_xx.csv（xx 为一个递增的数字）
- 将打包的“source_file”列在 pack_xxx_list.txt 中，放到 .\target 中
- 将“source_file”和相应的“source_file_flag”表格 #1 添加到 rar 文件中，并保存为 .\targetfile，即 Pack_xx.rar
- 从 .\temp 文件夹中删除 #1 和 #2 中的临时文件
以下是已存档的代码：允许选择给定数量的文件（n）并执行所有任务，然后重新运行批处理脚本，直到没有可用的文件

目标是在任务 #1 上选择文件以达到给定的总文件大小 (Mb)（如上面的示例代码，用于文件夹）- 因此每个创建的“pack_xx.csv”大小大致相同。并运行它，直到所有文件都“打包”，除非剩余文件小于给定的总大小。
