Introducing Sunburst Charts in FolderSizes v9.8: A Radiant New Way to Analyze Disk Space
FolderSizes v9.8 is here, and with it comes a visually stunning and intuitive new way to understand your disk space usage: the Sunburst Chart. This powerful new report type offers a dynamic and interactive method for visualizing hierarchical file systems, allowing you to quickly identify where your valuable disk space is being consumed.
What is a Sunburst Chart?
Imagine your file system, with its nested folders and subfolders, laid out in a circular, multi-level pie chart. That’s essentially what a Sunburst Chart is.
- The Center: The innermost circle of the Sunburst Chart represents the root folder you’ve selected for analysis.
- Radiating Rings: Each subsequent ring moving outwards represents the next level down in the folder hierarchy.
- Segment Size: The crucial aspect is that the size of each segment (or “slice”) within a ring is directly proportional to the size of the folder (and its contents) it represents relative to its parent. A larger segment means that folder is consuming more space.
This hierarchical, proportional representation makes it incredibly easy to spot large directories at a glance, no matter how deeply they’re buried.

How Sunburst Charts Revolutionize Disk Space Analysis
Traditional tree views and detailed listings are invaluable, but the Sunburst Chart in FolderSizes v9.8 brings a new dimension to disk space analysis:
- Immediate Visual Impact: Forget sifting through long lists of folders and numbers. The Sunburst Chart provides an instant overview. Large, space-hogging folders pop out visually, demanding your attention. The use of gradient sector fills further enhances visual clarity and aesthetic appeal.
- Intuitive Drill-Down: The Sunburst Chart isn’t just a static image. Simply click on any segment representing a folder, and the chart can re-center and expand on that specific branch, allowing you to explore deeper into its subfolder structure with the same intuitive visual cues. This makes navigating complex directory trees effortless.
- Contextual Understanding: By visualizing the entire hierarchy at once (or a significant portion of it), you gain a better understanding of how space is distributed across different branches of your file system. You can see not just that a folder is large, but also how its subfolders contribute to that size.
