我不相信它可以直接推導出來。這是我想到的
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 );
但它似乎並不准確
最好使用運行程序和一些命令來執行這種類型的檢查。
使用目錄中的文件，您將必須添加遞歸（1）（或自己執行循環，以獲取文件夾中的文件）。
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);

您也可以為此使用多個文件導入目錄樹：探索文件夾使用的空間
作為@jthi建議，這是使用 Run Program / Powershell（當然來自 JMP）的一種方法。

win10系統中，C盤各目錄的捲大小（包括隱藏檔案），具體要求為：
從C磁碟根目錄開始，
1.如果該目錄的子目錄超過3層，則可以擴展到第三層目錄，統計第三層目錄所包含的各個目錄各自的體積
2.如果該目錄的子目錄不超過3層，則將該目錄擴展至各自卷的最後一層目錄
