Understanding the disk map
Sunburst map may look unusual at first, but very soon you’ll get used to it and appreciate all its benefits.
Think of the map as if it was a flower. Colored petals are folders, grey ones are files. The wider is a petal, the larger is the object it represents. For your convenience, all segments are already sorted by size. The files and folders that are too thin to be visible separately are consolidated into semi-transparent petals.
Navigation in DaisyDisk is both flexible and easy to use. Just point to any folder to see its content on the sidebar. Click to drill down. Want to navigate to the parent folder? Simply click in the very center of the disk map.
In addition to files and folders, the sidebar list may contain the following objects:
- smaller objects are large groups of small files consolidated into a single item. Click on it to reveal the complete list, which may sometimes include thousands of files.
struck outfiles or folders have been deleted, renamed or moved outside DaisyDisk. If you see a lot of struck out objects, it is an indication to rescan the disk or folder so DaisyDisk can take account of the most recent changes.
- purple files and folders are restricted, i.e. they cannot be measured unless you scan the disk as administrator.
- hidden space is a virtual item that may be displayed in certain cases. It indicates that there is a significant amount of disk space hidden in restricted folders and other unreachable areas of the disk. Inside the hidden space, you may find purgeable space, other volumes (on APFS) and still hidden virtual items.
