楼上的朋友可能有点小小的误会楼主的意思了，
楼主朋友可能要现在已经分好区的空间大小，已用空间、剩余空间。
当然我也不敢保证谁对谁错，
我还是把我的理解 然后 也把代码贴出来让楼主看看吧
下面代码的功能：显示光驱当前分区，以及各个盘的总空间，剩余空间。
当然。如果要硬盘总空间，我们可以把所有空间加起来，就达到要求了。
希望下面的代码对楼主有用！

预先准备三个图标文件，用于树型控件中显示磁盘符号和文件夹的图像之用。
1、窗体上添加控件如下：
组合框控件 ComboBox1，树型控件 TreeView1，列表框控件 ListBox1，图像列表控件 ImageList1。
选中TreeView1，设置其ImageList属性为ImageList1。
2、设置属性
选中图像列表控件 ImageList1，在属性窗口里，选中属性Images，单击三个小点按钮，出现图像集合编辑器窗口，单击[添加按钮]，一一把准备好的图标文件进行添加，注意先后次序，如果不符合要求可以通过上下移动按钮重新改变次序。完成后单击[确定]。
运行图如下：
