DaisyDisk is a professional-grade disk space visualization and analysis tool designed specifically for macOS. It presents disk usage graphically through an intuitive interactive sunburst chart, enabling users to efficiently and accurately locate and clean up large files and useless data. This guide will detail its interface layout, complete workflow, and core usage tips.

I. Core Interface and Workspace Details

After launching DaisyDisk, the main interface is mainly divided into the following functional areas:

1. Disk Selection Panel (Left): Lists all connected local disks, volumes, and supported cloud storage services (such as Dropbox, Google Drive). Click any item to start scanning and analysis.
2. Visual Sunburst Chart (Main Workspace): This is the core of DaisyDisk. After scanning, the disk content is displayed in a multi-layered concentric sunburst chart.
   • Sectors: Each sector represents a file or folder, and its area is proportional to the disk space it occupies.
   • Colors: Usually colored by file type for easy differentiation.
   • Interaction: Hovering the mouse over a sector shows the path and size; clicking a sector expands it and focuses it in the center of the view, showing its internal contents; double-clicking a sector enters an independent, in-depth view of that folder.
3. Path Navigation Bar and Information Panel (Top):
   • Displays the full path of the current browsing location.
   • Displays detailed information such as the size and number of items of the currently selected item.
   • Provides navigation buttons such as “Go Back” and “Quick Look”.
4. Operation Toolbar (Bottom): Contains core operation buttons such as “Scan”, “Delete Files”, “Move to Trash”, etc.

II. Complete Workflow: From Analysis to Cleanup

The following are the complete steps for managing disk space using DaisyDisk.

1. Launch and Scan Disk

Steps:

1. Open DaisyDisk from the Applications folder or Launchpad.
2. In the disk list on the left side of the main interface, click the disk you want to analyze (e.g., “Macintosh HD”).
3. Click the “Scan” button in the lower right corner, or use the shortcut Command + R. DaisyDisk will begin quickly analyzing the directory structure of that disk.

2. Explore and Locate Large Files

After scanning is complete, the main workspace will display the complete sunburst chart.

How to operate:

1. Macro Browsing: The largest sectors are usually the files or folders occupying the most space. Move the mouse over these large sectors to view tooltip information.
2. Deep Dive:
   • Single-click a folder sector, and it will expand and “focus” to the center of the view, showing its internal contents.
   • Double-click a folder sector to enter an independent, detailed view of that folder.
   • Use the “Back” arrow in the top navigation bar or the shortcut Command + [ to return to the previous level.
3. Use List View Assistance: In the sunburst chart interface, press Command + 2 to switch to “List View”. This view displays files and folders in a traditional list sorted (by default in descending order of size), making it easy to find precisely.

3. Preview and Confirm Files

Before deleting files, be sure to confirm their contents.

How to operate:

1. In the sunburst chart or list view, click to select a file.
2. Click the “Quick Look” button (eye icon) in the top toolbar, or simply press the Spacebar.
3. The macOS Quick Look window will pop up, allowing you to preview documents, images, videos, and other file contents without opening the full application.

4. Delete Useless Files

After confirming the file is useless, you can delete it.

How to operate:

1. In the sunburst chart or list view, select one or more files/folders (hold the Command key for multiple selection).
2. Perform any of the following actions:
   • Click the “Move to Trash” button in the bottom toolbar.
   • Directly drag the selected sector from the DaisyDisk window to the Trash icon in the Dock.
   • Right-click the selected item and choose “Move to Trash”.
   • Use the shortcut Command + Delete.
3. DaisyDisk will pop up a confirmation dialog; click “Delete” to confirm. The deleted items will immediately disappear from the view, and the space they occupied will be freed.

5. Complete and Rescan

After cleaning some files, you can view the freed space.

How to operate:

1. Click the “Disk” button on the far left of the top navigation bar, or press Command + Up Arrow, to return to the disk root view.
2. Click the “Rescan” button in the bottom toolbar or press Command + R to update the disk usage view. You will find that the cleaned sectors disappear and available space increases.

III. Advanced Tips for Common Features

1. Scan multiple disks in parallel: In the left panel, you can click multiple disks to scan them sequentially. DaisyDisk will open an independent tab for each disk (at the top of the window), making it easy to switch and compare quickly.
2. Focus on a specific folder: In addition to scanning the entire disk, you can also drag a local folder directly into the DaisyDisk window for separate analysis, which is very suitable for checking the Downloads folder or project folders.
3. Use the “Keep” feature to mark important files: During cleanup, if you encounter a large file you are unsure about but do not want to delete for now, you can select it and click the “Keep” button in the toolbar (or press Command + K). Kept files will turn gray and be marked to avoid accidental deletion, making it convenient for you to handle them all at the end.
4. Filter displayed content: In List View (Command + 2), you can use the search box to filter files by name. In the sunburst chart view, you can view the distribution of specific file types (such as images, applications).

IV. Common Problems and Solutions

1. Problem: After scanning, files in the “Other” or “Unknown” category are shown to occupy a huge amount of space.

   Solution: “Other” usually includes system caches, user caches, plugins, virtual machine disks, etc. Use DaisyDisk to dive into these areas (such as `~/Library/Caches/`, `~/Library/Application Support/`) to safely clean some cache folders. But be cautious; it is best to only clean application caches whose source you clearly know.

2. Problem: Unable to delete certain files, prompting “The operation can’t be completed” or no permission.

   Solution: This is usually system-protected files or files requiring root permissions.

   • First, ensure the file does not belong to a running application.
   • For files in the user directory, try deleting them in Finder.
   • For system-level files, unless you are very sure of their purpose, it is not recommended to force deletion to avoid affecting system stability.
3. Problem: Cloud storage (Dropbox/Google Drive) scanning is slow or cannot connect.

   Solution:

   • Ensure the corresponding cloud desktop client is logged in and running properly.
   • Cloud scanning speed is limited by network bandwidth and cloud API response speed, usually slower than local scanning.
   • Check whether DaisyDisk has permission to access these cloud folders (System Preferences > Security & Privacy > Privacy > Files and Folders).
