磁盘查看器

磁盘查看器以图形的形式显示了您的磁盘卷的空间利用情况。
一个非常好用的工具，它回答了下面的问题，“我的磁盘空间哪儿去了啊？”。

After launching, DiskUsage shows only a white window with all mounted volumes as tabs at the top. You'll have to choose the one you're interested in and click Scan to start chugging through the disk. For larger disks this can take some time... While you wait, you may switch to a different tab and start exploring that volume or begin the scan process there as well.
It's not recommended to start several concurrent scan processes on the same physical disk, as the constant repositioning of the heads of the drive will only extend the wait.

不同层次的同心圆代表了文件系统中的不同等级。 在上图中，圆环中心代表了 /boot/home/ 文件夹。而圆环外的每个图块都代表了 /boot/home/ 文件夹下的一个文件或者文件夹。而更外层的图块则代表了更深一层等级的文件层次。当然，您可能需要调节窗口的大小来容纳深层地的文件夹。

在您的鼠标移动到一个图块上时，关于该文件或者文件夹的信息将会呈现在底部的状态栏里。

Right-clicking a segment offers a context menu to Get info, Open (with Tracker), Open with another suitable application or Rescan that particular folder.
Left-clicking a segment makes that file/folder the center circle.
Left-clicking the center circle moves you up one level.

您可以从磁盘查看器中拖拽文件或者文件夹到其他的程序，桌面或者其他的Tracker窗口完成复制。反之，如果把磁卷或者文件夹拖拽至磁盘查看器窗口将会把他们放置在圆环的中央进行显示。

You can also use the Tracker add-on from the context menu of any folder to start DiskUsage with that particular location.
