如何使用 JSL 直接获取指定文件夹的卷？例如这个文件夹：
C:\Windows
谢谢！
内容组织视窗Re: 如何使用 JSL 直接获取指定文件夹的卷？我不相信它可以直接推导出来。这是我想到的
Names Default To Here( 1 );
theList = Files In Directory( "C:\Windows" );
totSize = 0;
For Each( {theFile}, theList,
totSize = Sum( totSize, File Size( "C:\Windows\" || theFile ) )
);
Show( totSize );
但它似乎并不准确
Re: 如何使用 JSL 直接获取指定文件夹的卷？谢谢吉姆！
Re: 如何使用 JSL 直接获取指定文件夹的卷？Re: 如何使用 JSL 直接获取指定文件夹的卷？最好使用运行程序和一些命令来执行这种类型的检查。
使用目录中的文件，您将必须添加递归（1）（或自己执行循环，以获取文件夹中的文件）。
Names Default To Here(1);
lookup_dir = "C:\Windows\";
file_list = Files In Directory(lookup_dir, recursive(1));
file_sizes = Transform Each({cur_file}, file_list,
File Size(lookup_dir || cur_file)
);
sum(file_sizes);

您也可以为此使用多个文件导入目录树：探索文件夹使用的空间
Re: 如何使用 JSL 直接获取指定文件夹的卷？作为@jthi建议，这是使用 Run Program / Powershell（当然来自 JMP）的一种方法。

在win10系统中，C盘各个目录的卷大小（包括隐藏文件），具体要求是：
从 C 盘根目录开始，
1、若本目录的子目录超过3层，可以扩展到第三层目录，统计第三层目录所含各目录各自的体积
2、若此目录的子目录不超过3层，则扩展此目录至各自卷的目录最后一层的统计信息
