管理硬盘空间是一场持久战，尤其是在存储空间有限的情况下。如果您下载大量文件，您会突然发现自己的空间不足。
如果您发现自己的硬盘容量已用完，但不确定哪些文件占用了空间，您需要一个磁盘空间分析器。
磁盘空间分析器提供对硬盘驱动器的可视化分析，使您能够确定哪些文件占用了空间、最大文件潜伏在驱动器上的位置、重复文件等等。
1.WinDirStat
WinDirStat是最好的磁盘空间分析工具之一，当然也是最受欢迎的工具之一。它易于使用、开源，提供对驱动器的详细分析，并具有硬盘驱动器的巨大视觉显示。
您也可以从WinDirStat管理计算机上的文件。右键单击文件或文件夹会打开上下文菜单。从这里，您可以将文件移动到回收站(Recycle Bin)、永久删除、打开目录等等。
另一个方便的 WinDirStat(WinDirStat)功能是搜索特定的文件类型。如果您有一堆单一文件类型并想要找到它们（可能将它们统一在一个文件夹中），您可以搜索并显示它们在硬盘驱动器上的隐藏位置。
2. DiskSavvy
DiskSavvy是一个功能强大的磁盘空间分析工具，具有相当多的工具。您可以免费下载和使用DiskSavvy。但是，免费版本将分析限制为 500,000 个文件。这意味着DiskSavvy可用于分析特定文件夹，但不能处理整个硬盘驱动器。
尽管如此，DiskSavvy工具使它成为硬盘驱动器分析的一个有价值的选择。您可以选择将文件查看为各种饼图、按扩展类型分类、按媒体或文档类型进行分析、创建或修改的时间和日期等等。DiskSavvy分析向导包含大量预设分析设置列表，可轻松在搜索选项之间切换。
DiskSavvy还允许您扫描和分析网络设备。这意味着您可以将NAS（网络附加(Network Attached)存储）连接到DiskSavvy并可视化您的磁盘使用情况。
总的来说，DiskSavvy是一个很棒的磁盘分析选项。免费版的 500,000 个文件限制是唯一的主要缺点。升级到DiskSavvy Pro将花费 50 美元购买有限许可证。
完成磁盘分析后，您可能需要对其进行格式化。查看适合您的硬盘管理需求的最佳格式化和分区实用程序。(best formatting and partitioning utilities)
3. JDisk 报告(3. JDisk Report)
另一个出色的磁盘分析选项是JDisk Report，这是一个免费的Java工具，可用于分析Windows、macOS 和Linux上的文件。
现在，JDisk Report很慢。在灌木丛中没有殴打。就是这样。但是，一旦JDisk Report完成分析，您将看到一个巨大的硬盘驱动器饼图可视化。如果您愿意，可以将饼图切换为条形图。
单击饼图的各个部分会降低文件系统级别。例如，单击Program Files打开Program Files 文件(Program Files)夹的分析。
碎片整理曾经是加速硬盘驱动器的首选选项。但是您应该对 SSD 进行碎片整理以提高速度( should you defrag an SSD for a speed boost)吗？
4. 树大小免费(4. TreeSize Free)
TreeSize Free是一个方便的磁盘空间分析工具，具有不错的可视化选项。
TreeSize Free在左侧窗口中显示您的硬盘驱动器，详细说明大小、修改日期和文件路径。选择TreeMap Chart 会将(TreeMap Chart)窗口视图切换为一系列框，每个框都说明了一个文件夹及其在驱动器上的当前大小。您还可以使用滑块来修改显示的详细级别，降低级别以显示更少的文件和文件夹，反之亦然。
TreeSize Free具有与Windows文件资源管理器类似的(Windows File Explorer)GUI。您会在顶部工具栏中找到磁盘分析选项，以及不同的视图和其他工具。
磁盘分析只是您在计算机上保持标签的一种方式。查看这些可用于改善 PC 健康状况的其他工具(these other tools you can use to improve your PC’s health)。
5. 空间嗅探器(5. SpaceSniffer)
SpaceSniffer是一款免费磁盘空间分析器，专注于硬盘存储的可视化。选择要分析的硬盘驱动器后，SpaceSniffer窗口立即开始填充瓷砖。磁贴代表硬盘驱动器的各个文件夹，以及每个文件夹当前使用的空间。
选择磁贴可将您向下移动到文件夹和文件的详细信息级别。您可以使用集成工具过滤和比较您的文件和文件夹，以及保存自定义布局或搜索选项以供将来使用。
使用SpaceSniffer进行磁盘分析的方法一开始会让人感到有些不知所措。有很多方块，有些在闪烁，当你选择它们时情况会发生变化。但是一旦您适应了这种风格，您就会发现SpaceSniffer是一款出色的磁盘分析器。
6. Windows 集成工具(6. Windows Integrated Tool)
Windows实际上有一个集成的磁盘分析工具。它不是最华丽的，并且缺少专用第三方选项中的许多可用选项。不过，这是一个方便的工具，值得一提。
按Windows Key + I ，然后在搜索栏中输入Storage 。选择第一个选项以打开存储(Storage)设置。硬盘分析器将填充各种条，指示您的文件和文件夹。选择一个文件夹会将分析扩展到下一个级别。
什么是最好的磁盘空间分析器？(What Is the Best Disk Space Analyzer?)
就磁盘空间分析器而言，WinDirStat仍然是最佳选择之一。它是完全免费的、开源的，并且做得很好。它甚至在窗口底部具有基于块的大型可视化器，并且还具有一些方便的过滤和分析工具。
如果您需要比WinDirStat提供的更多功能，DiskSavvy是一个不错的选择。它的集成工具是最好的工具之一，具有大量预设的分析选项。Pro升级成本可能会让一些用户望而却步，但这是个人选择。

6 Best Disk Space Analyzers To Find Lost Gigabytes
Managing your hard drive spaсe is a constant battle, especially if you havе limited storage. If you download lots of files, you’ll ѕuddenly find yourself running out of ѕpace.
If you find yourself running out of hard drive capacity but are unsure which files are taking up space, you need a disk space analyzer.
A disk space analyzer provides a visual analysis of your hard drive, allowing you to figure out which files are taking up space, where the largest files lurk on your drive, duplicate files, and much more.
1. WinDirStat
WinDirStat is one of the best disk space analyzer tools and is certainly one of the most popular. It is easy to use, open-source, provides a detailed analysis of your drives, and features a giant visual display of your hard drive.
You can manage the files on your computer from WinDirStat, too. Right-clicking a file or folder opens the context menu. From here, you can move files to the Recycle Bin, delete permanently, open the directory, and more.
Another handy WinDirStat feature is searching for a specific file type. If you have heaps of a single file type and want to locate them (perhaps to unify them in a single folder), you can search and reveal where they’re hiding on your hard drive.
2. DiskSavvy
DiskSavvy is a powerful disk space analyzer tool with a considerable range of tools. You can download and use DiskSavvy for free. However, the free version limits analysis to 500,000 files. That means DiskSavvy is useful for analyzing specific folders, but won’t handle an entire hard drive.
Still, the DiskSavvy tools make it a worthwhile option for hard drive analysis. There are options to view your files as various pie charts, to categorize by extension type, to analyze by media or document types, the time and date of creation or modification, and many more. The DiskSavvy analysis wizard contains an extensive list of pre-set analysis settings, making it easy to switch between search options.
DiskSavvy also allows you to scan and analyze network devices, too. That means you can connect your NAS (Network Attached Storage) to DiskSavvy and visualize your disk usage.
Overall, DiskSavvy is a great disk analysis option. The 500,000 file limitation in the free version is the only major downside. Upgrading to DiskSavvy Pro will set you back $50 for a limited license.
Once you finish analyzing your disk, you might want to format it. Check out the best formatting and partitioning utilities for your hard drive management needs.
3. JDisk Report
Another great disk analysis option is JDisk Report, a free Java tool you can use to analyze files on Windows, macOS, and Linux.
Now, JDisk Report is slow. There’s no beating about the bush. That’s just how it is. However, once JDisk Report completes the analysis, you’re treated to a giant pie chart visualization of your hard drive. You can switch the pie chart out for a bar chart if you prefer.
Clicking on the segments of the pie chart takes you down a file system level. For example, clicking Program Files opens the analysis of the Program Files folder.
Defragging was once a go-to option for speeding up your hard drive. But should you defrag an SSD for a speed boost?
4. TreeSize Free
TreeSize Free is a handy disk space analyzer tool with a decent visualization option.
TreeSize Free displays your hard drive in the left window, detailing sizes, modification dates, and file paths. Selecting the TreeMap Chart switches the window view into a series of boxes, each one illustrating a folder and its current size on your drive. You can also use a slider to modify the level of detail on display, decreasing the level to show fewer files and folders or vice versa.
TreeSize Free has a similar GUI to the Windows File Explorer. You’ll find disk analysis options in the top toolbar, as well as different views and other tools.
Disk analysis is just one way for you to keep tabs on your computer. Check out these other tools you can use to improve your PC’s health.
5. SpaceSniffer
SpaceSniffer is a free disk space analyzer that focuses on the visualization of your hard drive storage. After selecting your hard drive for analysis, the SpaceSniffer window immediately begins filling with tiles. The tiles represent the various folders of your hard drive, along with the space each is currently using.
Selecting a tile moves you down a level of detail into the folders and files. You can filter and compare your files and folders using integrated tools, as well as save the custom layout or search options for future use.
The SpaceSniffer approach to disk analysis can feel a little overwhelming at first. There are lots of squares, some are flashing, and things change when you select them. But once you adjust to the style, you’ll see that SpaceSniffer is an excellent disk analyzer.
6. Windows Integrated Tool
Windows actually has an integrated disk analysis tool. It isn’t the most flashy and lacks many of the options available in the dedicated third-party options. It’s a handy tool, though, and it’s worth a mention.
Press Windows Key + I, then input Storage in the search bar. Select the first option to open the Storage settings. The hard drive analyzer will populate the various bars, indicating your files and folders. Selecting a folder extends the analysis down to the next level.
What Is the Best Disk Space Analyzer?
As far as disk space analyzers go, WinDirStat is still one of the best options. It is completely free, open-source, and does a great job. It even features the massive block-based visualizer at the bottom of the window and has some handy filtering and analysis tools, too.
If you need more power than WinDirStat offers, DiskSavvy is a great option. Its integrated tools are amongst the best available, with plenty of pre-set analysis options. The Pro upgrade cost might put some users off, but that’s a personal choice.
