DaisyDisk

DaisyDisk needs to scan the disk to create a map of its files and folders. Once the initial scan is completed, DaisyDisk doesn't keep displayed information up to date and reflects only changes to disk made through interaction with DaisyDisk. DaisyDisk can scan multiple disks in parallel.^[10]

With v4.5^[11] of DaisyDisk, support for APFS was added.^[12]

DaisyDisk displays the contents as a color-coded sunburst diagram, resembling the petals of a daisy.^[13] The interface places the root of the hard drive at the center of this daisy, and displays a hierarchical structure of that hard drive's file system that radiates from that center. This daisy is color-coded to differentiate between folders, while files themselves are always displayed as gray. In the right sidebar of the interface, DaisyDisk also provides a legend for these color codes. When hovering over a file or folder, the right sidebar of the interface updates with contextual information such as the file or folder name and their absolute path.^[14] When clicking on a folder on the daisy, a new daisy is displayed with the chosen folder as its root. The interface shows a "breadcrumb trail" of the current folder right above the sunburst diagram.^[6]

DaisyDisk provides a Trash-like collector icon in the lower left of its interface where files and folders can be dragged and dropped for deletion.^[14]

As of DaisyDisk v3, a specialized version of the app exists for Mac users with Retina Displays.^[15]

One of the ways DaisyDisk integrates with the Mac features is through its support of the Quick Look function, which is included in Mac OS X v10.5 "Leopard" and later. Hovering over any file or folder in DaisyDisk's interface and pressing space bar utilizes Quick Look and displays additional information about that file or folder in regards to its location and contents.^[13]
