Over a period of time we encounter insufficient disk space issues which might have been caused by poor preventive maintenance, low budget for a higher capacity disk (not all of us could afford a Terabyte of hard disk), or lack of discipline (we like to download everything and keep them forever even we don’t need them for future use!).在过去一段时间我们所遇到的磁盘空间不足的问题，可能已造成穷人的预防性维修，低预算，高容量磁盘（不是所有的我们能够负担1 TB的硬盘） ，或缺乏纪律， （我们想下载一切，让他们永远甚至我们不需要他们以供未来使用！ ） 。
One way to free up disk space is by deleting the temporary files using Windows Disk Cleanup. While it could free up temporary files it doesn’t handle the other files. What if the files that you want to clean up are not temporary files? It is hard to find what contributes to a hard disk usage specially if they are buried in several layers of folders.方法之一，腾出磁盘空间是删去临时文件使用的是Windows磁盘清理的同时，它可以自由行动的临时文件，它不处理其他文件。什么，如果你的档案要清理没有临时文件呢？是很难找到什么有助于硬盘的使用，特别如果他们是埋在以下几个层次的文件夹中。
I accidentally found a freeware我不小心发现一个免费 WinDirStat windirstat while I was researching for虽然我是研究为 treemaps as a substitute for pie charts. The final output of this tool is a treemap breakdown of every file in your hard disk:作为一个替代的饼图表。最后产出这个工具是一个treemap分项的每个文件在您的硬盘：
To use this freeware you will need to download and install WinDirStat from their若要使用此免费您将需要下载并安装windirstat从他们的 website网站 , run it and choose the drive that you want to analyze, in the example below I have chosen my primary drive C: ，运行它并选择驱动器您要分析，在下面的例子中我选择了我的主要驱动器C ：
For my 80GB disk with about 10% free disk space, the analysis run for less than 10 minutes which is not bad.我的80 GB的磁盘与约10 ％的可用磁盘空间，分析运行不到10分钟，这是不坏。
After the analysis step, the output of my C drive is this:分析后的步骤，输出我的C驱动器是这样的：
At first it looks like modern art or an intimidating cryptic message from space, but after a few moments you will realize that each box represents a file and the size of the box is proportional to the size of the file. The bigger the file, the bigger the box. In summary, you are seeing the whole hard disk with every file visually represented according to size.在第一，它看起来像现代艺术或恐吓潜讯息从空间，但经过几分钟，你会认识到，每个方块代表一个文件和大小的方块是成正比的档案的大小。越大，档案，更大的框。总括来说，您所看到的整个硬盘上的每个档案的视觉代表根据大小。
Each of the colors used represent a file and it is shown as a legend in the upper right corner. In the example below, I clicked the big red box and it shown the file type which is a pst (Outlook data) file:每所用的颜色代表一个文件，这是作为一个传说，在右上角。在下面的例子，我点击大红色的框，它显示的文件类型，这是太平洋标准时间（ Outlook数据）档案：
The upper left part of the window shows the path of the file or folder that you clicked:左上角的一部分，窗口显示的路径的文件或文件夹您点击：
The number at the right side shows the relative contribution of the file to the parent folder.人数在右侧显示的相对贡献的文件到父文件夹。
The files within the same folder are displayed together. If you click a folder name all of the boxes inside that folder will be highlighted in white:文件在同一文件夹中显示在一起。如果您单击一个文件夹名称，所有的箱子夹内的文件将突出表现在白纸：
This means if I delete the Outlook folder all of this boxes in red will be gone and a huge amount of space in my disk is freed-up. This “coupling” feature of the path to the box on the map is very intuitive and novice users will easily get used to it.这意味着，如果我删除Outlook文件夹这一切，饭盒的红色将会消失，以及大量的空间，在我的磁盘是释放行动。这种“耦合”功能的路径框，在地图上是非常直观和新手用户将很容易地使用它。 You can either delete the box or the file under the path.您可以删除的方块，或该文件下的路径。
After you delete an item it will redraw the map within a few seconds.之后，您删除一个项目将重绘地图内的几秒钟。
By the way, an extra feature is that it lets you delete the files securely by not letting you “undelete” or recover from the recycle bin:由的方式，额外的特点是，它可以让您删除档案安全，没有让您“删除”或恢复从回收站：
If you choose this Delete (no way to undelete) the deleted files will not occupy the recycle bin thus really freeing up the disk space. Deleting to recycle bin means you only are moving the files to the recycle bin – they will still exist on the hard disk. If you are sure you won’t be needing the file, choose Delete (no way to undelete) .如果您选择此删除（没办法删除）删除的文件将不会占据回收站，从而真正腾出了磁盘空间。删去，以回收站意味着你不仅是移动文件到回收站-他们仍然会存在于硬盘，如果你确信你会不会需要该文件，选择删除（没办法删除） 。

One of my favorite treemap application is a Google news page generator:其中我最喜爱的treemap的应用是一个Google新闻网页发生器： http://www.marumushi.com/apps/newsmap/newsmap.cfm
