DaisyDisk for Mac v4.12 Find Useless Files Chinese Activated Version Download

DaisyDisk for Mac is a professional disk space visualization and analysis tool. It intuitively displays disk usage through a unique interactive circular sunburst chart, helping users quickly locate and clean up files and folders that take up large amounts of space, thereby efficiently managing Mac storage space. Whether the system drive is full or an external drive is running out of space, this tool gives you a clear overview.

I. Core Interface and Workspace Details

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

1. Disk Selection Panel: Located on the left side of the window. Lists all mounted disk volumes (such as “Macintosh HD”) and the “Scan Folder” option. Click any item to start analysis.
2. Visualization Analysis Area (Sunburst Chart): Occupies the main part of the window. Displays disk contents in the form of nested rings. Each sector represents a file or folder, and its area is proportional to the space it occupies. Colors are usually used to distinguish file types.
3. Path Navigation Bar: Located at the top of the window. Displays the full path currently browsed in the sunburst chart and allows you to quickly jump to the parent directory.
4. Information Panel: Located on the right side or bottom of the window (depending on the view mode). Displays detailed information about the currently selected item, including name, size, number of files, modification date, etc.
5. Toolbar: Contains core operation buttons such as “Scan”, “Rescan”, “Quick Look”, “Delete”, etc.

II. Complete Operation Process: From Analysis to Cleanup

1. Start Analysis and Select Scan Target

2. Browse and Analyze Disk Usage

3. Preview and Confirm File Contents

4. Delete Useless Files to Free Up Space

5. Complete and Rescan

III. Advanced Tips for Common Features

1. Focus on “Other” Storage Space: The “Other” category in macOS system reports is often difficult to clean up. After scanning the entire disk with DaisyDisk, you can visually identify the largest components of “Other” space by browsing system folders such as “Library”, “Application Support”, “Caches”, etc. This technique is recommended by many Mac technical bloggers.
2. Scan Multiple Disks in Parallel: Click multiple disks in the left panel to scan them sequentially; DaisyDisk will take advantage of multi-core CPUs to scan in parallel, improving efficiency. According to Apple developer documentation, proper use of multithreading can significantly improve the processing speed of I/O-intensive tasks.
3. Use the “Keep” Feature to Mark Important Files: During cleanup, if you encounter a large file that you are unsure about but do not want to delete for now, you can select it and use the shortcut Command + B to mark it as “Keep” (it will turn gray). This helps avoid accidental deletion during complex cleanup processes.
4. Export Scan Snapshot: Through the menu bar “File” → “Export Scan Snapshot…”, you can save the current disk analysis chart as an image for later comparison or archiving. This is very useful for regularly checking disk health.

IV. Common Problems and Solutions

1. Problem: Cannot delete certain system files, prompting “The operation can’t be completed”.
   Solution: This is a normal system protection mechanism. DaisyDisk cannot directly delete files protected by System Integrity Protection (SIP) or certain files in use. For such files, it is recommended to first confirm whether they can be safely deleted, then try operating in Safe Mode, or use specialized system cleaning tools. For files in user directories, ensure you have the appropriate permissions.
2. Problem: Scan results are inaccurate or not updated in real time.
   Solution: First try clicking “Rescan” (Command+R). If the problem persists, it may be that some temporary files were modified by the system or applications after scanning. You can quit and restart DaisyDisk. Additionally, ensure you have Full Disk Access permission for the scan target disk (check and add DaisyDisk in “System Settings” – “Privacy & Security” – “Full Disk Access”).
3. Problem: How to analyze external hard drives or network drives?
   Solution: Ensure the external drive is properly mounted on the macOS desktop or Finder sidebar. After launching DaisyDisk, the drive will usually appear in the left disk list; click to scan. For network drives, ensure they are stably connected and have read permissions.
4. Problem: DaisyDisk cannot recognize my APFS-formatted disk.
   Solution: DaisyDisk fully supports APFS (Apple File System). If it cannot be recognized, check whether the macOS version is 10.13 or higher. Also, confirm the disk has no hardware failure. You can verify the disk in “Disk Utility”.
5. Problem: After deleting files, available space does not increase.
   Solution: First check whether the Trash has been emptied. macOS’s “Trash” itself also occupies space. Second, some system cache files will be automatically recreated by the system after deletion. It is recommended to use the “Rescan” feature to view the latest status. If the problem persists, it may be that Time Machine local snapshots are occupying space; try turning Time Machine off and on again.
6. Problem: Scanning speed is very slow.
   Solution: Scanning speed depends on disk size and number of files. If the disk contains a large number of small files (e.g., development projects or email archives), scanning may be slower. Try closing other applications that are reading/writing to the disk. Also, ensure your Mac uses an SSD rather than a traditional mechanical hard drive, which would be much slower.
7. Problem: How to recover accidentally deleted files?
   Solution: If you chose “Move to Trash”, you can find and restore the files in the Trash. If you chose “Delete Permanently”, they cannot be recovered through DaisyDisk. It is recommended to immediately stop using the disk and use professional data recovery software (such as Disk Drill) to attempt recovery. However, success is not guaranteed.
8. Problem: DaisyDisk’s “Quick Look” feature cannot preview certain files.
   Solution: “Quick Look” relies on macOS’s built-in preview framework. Some special format files (such as PSD or RAW photos) may require additional Quick Look plugins to preview. You can search online and install the corresponding plugins.
