DaisyDisk for Mac v4.9 Find and Delete Useless Files Chinese Activated Version Download

DaisyDisk is a visual disk space analysis tool designed specifically for macOS. It presents disk usage intuitively through a beautiful interactive sunburst chart (also known as a fan chart), helping you quickly locate and clean up folders and files that take up large amounts of space, thereby efficiently managing your Mac’s storage.

I. Core Interface and Workspace Details

After launching DaisyDisk, you will see a clean and informative main interface, mainly divided into the following areas:

1. Disk Selection Panel: Located on the left or top of the window. Displays all analyzable volumes on your Mac (such as “Macintosh HD”, external drives, network drives, etc.) in a list.
2. Visual Analysis Chart (Core Workspace): Occupies the largest area in the center of the window. This is an interactive “sunburst chart” or “fan chart”.
   • Structure: Radiates from the center outward, with each sector representing a folder or file.
   • Area and Color: The sector area is proportional to the disk space occupied by the item. Colors are usually used to distinguish file types or levels; items at the same level have similar colors.
   • Interaction: Click any sector to expand it to the center and display its contents. Hover over a sector to show the item’s path, size, and file count.
3. Path Navigation Bar and Information Panel: Usually located at the top or bottom of the window.
   • Path Breadcrumbs: Shows the full folder path currently being viewed in the analysis chart; you can click any parent directory to jump quickly.
   • Detailed Information: Displays the name, size, number of contained items, and last modified date of the currently selected item.
4. Toolbar: Contains core action buttons such as “Scan”, “Rescan”, “Show/Hide File List”, “Delete”, etc.
5. File List View (Optional): Click the list icon in the toolbar to switch to or display side-by-side a traditional file list sorted by size for precise comparison.

II. Complete Workflow: From Analysis to Cleanup

1. Launch and Select Scan Target

Step 1: Launch DaisyDisk. Open the software from the Applications folder or Launchpad.

Step 2: Select scan target. In the disk selection panel, click the name of the disk volume you want to analyze (e.g., “Macintosh HD”).

Step 3: Start scanning. Click the “Scan” button to the right of the target disk, or double-click the disk name. Shortcut: Command + R (rescan the selected disk).

2. Interactive Disk Space Analysis

After the scan is complete, the visual analysis chart will automatically expand.

Step 4: Explore large files.

• Click the largest sector to “zoom” it to the center of the view and see its internal composition.
• Repeat this operation, following the path with the largest area; this usually quickly locates the folders or files taking up the most space.

Step 5: Use path navigation. Use the path breadcrumb navigation bar at the top to jump back to any parent directory at any time.

Step 6: View file list. Click the “Show File List” button in the toolbar (or use the shortcut Command + 2) to open the list view on the right for more precise size comparison and sorting.

3. Locate and Preview Suspicious Items

Step 7: Preview file contents. Select a file (such as a large video, PDF, archive, etc.) in the analysis chart or list, and press the Space bar to preview its contents using macOS Quick Look and confirm whether it is useless.

Step 8: Show in Finder. Right-click any item in the analysis chart and select “Show in Finder”, or use the shortcut Command + Shift + F. This helps you further confirm the file location and context.

4. Safely Delete Useless Files

Step 9: Select items to delete. Select one or more files/folders in the analysis chart or list.

Step 10: Execute deletion. There are three main ways:

1. Click the “Delete” button in the toolbar.
2. Drag the selected items directly to the “Trash” icon in the Dock.
3. Right-click and select “Move to Trash”. Shortcut: Command + Delete.

Step 11: Empty the Trash. The delete operation only moves files to the Trash. To truly free up disk space, you need to return to Finder, right-click the Trash in the Dock, and select “Empty Trash”.

5. Export Scan Results (Optional)

Step 12: Export analysis. If you need to save or share scan results, you can click “File” -> “Export Scan Info…” in the menu bar. You can export the current view as a text file or CSV file, recording the size information of files and folders.

III. Advanced Tips for Common Features

1. Focus on “Other” Storage Space: DaisyDisk excels at parsing files categorized as “Other” in macOS Storage Management. Carefully scan the ~/Library directory (especially Caches, Application Support, Logs folders) and system temporary folders to often find stale cache and log files.
2. Use the “Keep” Feature to Mark Important Files: During analysis, if you encounter a large file you don’t want to accidentally delete (such as important project data), you can right-click it and select “Keep”. Kept items are displayed with a special mark to remind you to skip them during cleanup.
3. Compare Multiple Scan Results: Regularly scan the same disk and observe changes in the size of specific folders (such as Downloads, Videos) to manage space growth more effectively.
4. Analyze External Drives and Network Volumes: DaisyDisk can analyze not only internal hard drives but also external USB drives, portable SSDs, or mounted network drives (such as NAS), using the same method.
5. Keyboard Navigation: In the analysis chart, use the keyboard arrow keys to quickly switch selection between different sectors, improving efficiency.
