moveFirst Method

Resets the current item in an Enumerator object to the first item.

function moveFirst()

Remarks

If there are no items in the collection, the current item is set to undefined.

Example

In following example, the moveFirst method is used to evaluate members of the Drives collection from the beginning of the list:

function ShowDrives()
{
    var s = "";
    var bytesPerGB = 1024 * 1024 * 1024;

    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var e = new Enumerator(fso.Drives);

    e.moveFirst();
    while (e.atEnd() == false)
    {
        var drv = e.item();

        s += drv.Path + " - ";

        if (drv.IsReady)
        {
            var freeGB = drv.FreeSpace / bytesPerGB;
            var totalGB = drv.TotalSize / bytesPerGB;

            s += freeGB.toFixed(3) + " GB free of ";
            s += totalGB.toFixed(3) + " GB";
        }
        else
        {
            s += "Not Ready";
        }

        s += "\n";

        e.moveNext();
    }
    return(s);
}
