function ShowDriveInfo1(drvPath)
{
   var fso, drv, s ="";
   fso = new ActiveXObject("Scripting.FileSystemObject");
   drv = fso.GetDrive(fso.GetDriveName(drvPath));
   s += "Drive " + drvPath.toUpperCase()+ " - ";
   s += drv.VolumeName + "<br>";
   s += "Total Space: " + drv.TotalSize / 1024;
   s += " Kb" + "<br>"; 
   s += "Free Space: " + drv.FreeSpace / 1024;
   s += " Kb" + "<br>";
   Response.Write(s);
}

2.使用 Folder 和 FileSystemObject 對象，來操作文件夾和獲得有關它們的信息

function ShowFolderInfo()
{
   var fso, fldr, s = "";
   // 獲得 FileSystemObject 的實例。
   fso = new ActiveXObject("Scripting.FileSystemObject");
   // 獲得 Drive 對象。
   fldr = fso.GetFolder("c:");
   // 打印父文件夾名。
   Response.Write("Parent folder name is: " + fldr + "<br>");
   // 打印驅動器名字。
   Response.Write("Contained on drive " + fldr.Drive + "<br>");
   // 打印根文件名。
   if (fldr.IsRootFolder)
      Response.Write("This is the root folder.");
   else
      Response.Write("This folder isn't a root folder.");
   Response.Write("<br><br>");
   // 用 FileSystemObject 對象創建新的文件夾。
   fso.CreateFolder ("C:\\Bogus");
   Response.Write("Created folder C:\\Bogus" + "<br>");
   // 打印文件夾的基本名。
   Response.Write("Basename = " + fso.GetBaseName("c:\\bogus") + "<br>");
   // 刪除新創建的文件夾。
   fso.DeleteFolder ("C:\\Bogus");
   Response.Write("Deleted folder C:\\Bogus" + "<br>");
}
