DaisyDisk for Mac v4.21.3 Graphical Disk Usage Display Chinese Activated Version Download

DaisyDisk is a disk space analysis tool designed specifically for macOS. It visually displays disk usage through an interactive, visual ‘Sunburst Diagram’, helping users quickly locate and clean up folders and files that occupy large amounts of space. The software is particularly good at uncovering vaguely categorized ‘Other’ files in the macOS system. Its design philosophy is to transform complex disk data into an intuitive graphical interface, making disk cleanup efficient and intuitive.

1. Core Interface and Workspace Detailed Explanation

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

1. Disk Selection Panel (Left): Lists all mounted disk volumes (such as ‘Macintosh HD’, ‘Data’, etc.) and common scan locations (such as ‘User Folder’). Click any item to start scanning and analysis.
2. Visualization Analysis Area (Central Main Area): This is the core of DaisyDisk. After scanning is complete, a colorful ‘Sunburst Diagram’ is displayed.
   • Sector Blocks: Each sector represents a folder or file, and its area is proportional to the disk space it occupies.
   • Color Differentiation: Different colors usually represent different file types or directory levels for easy visual distinction.
   • Interactive Operations: Click any sector to expand it to the center and display its internal contents. Hover the mouse over a sector to display detailed information such as the path and size of the item.
3. Path Navigation Bar and Information Panel (Top):
   • The top displays the full path of the current browsing location.
   • The right side displays specific information about the currently selected item, such as name, size, number of contained items, modification date, etc.
4. Operation Toolbar (Bottom): Contains core function buttons such as ‘Scan’, ‘Delete’, ‘Quick Look’, etc.

2. Complete Operation Process: From Analysis to Cleanup

The following are the complete steps from launching the software to completing cleanup.

1. Launch and Scan Disk

Operation Steps:

1. Find and open DaisyDisk in 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 (for example, ‘Macintosh HD’).
3. The software will immediately start scanning. You will see a dynamic scanning animation in the central area, while the bottom status bar shows the scanning progress and the size of files analyzed so far.

Shortcut: After selecting a disk, press Command + R to rescan the current disk.

2. Browse and Analyze Visualization Charts

Operation Steps:

1. Deep Exploration: In the central sunburst diagram, click any colored sector. The sector will move to the center of the diagram and expand, showing the subfolders and files it contains.
2. Return to Upper Level: Click the upper-level folder name in the top path navigation bar, or press Command + [ (left bracket) to return to the previous level.
3. View File Details: Hover the mouse pointer over any sector, and a tooltip will pop up showing its name, size, and path. More detailed information will be displayed synchronously in the right information panel.
4. Quick Preview of File Contents: Select a file sector (such as images, PDFs, text files), then press the Spacebar to invoke macOS’s ‘Quick Look’ function to preview the content without opening the native application.

3. Mark and Delete Unnecessary Files

Operation Steps:

1. Mark Items to Delete: During browsing, for files or folders confirmed to be deleted, right-click the corresponding sector and select ‘Move to Trash…’ from the context menu. A quicker way is to directly drag the sector to the ‘Trash’ area in the lower right corner of the interface.
2. View Marked Items: All marked items are temporarily collected in the ‘Trash’ panel in the lower right corner of the interface. Click the panel to expand it and view the list of all items to be deleted and the total estimated space that can be freed.
3. Execute Deletion: In the ‘Trash’ panel, after confirming the list is correct, click the ‘Delete’ button in the lower right corner. The software will pop up a confirmation dialog again, reminding you that the deletion operation is irreversible. Click ‘Delete’ to permanently delete these files.

4. Export Scan Report

You can save the disk analysis results as a report for archiving or sharing.

Operation Steps:

1. In the menu bar, click ‘File’ > ‘Export Chart As…’.
2. Select the save format (such as PNG image) and location, then click ‘Save’.

Shortcut: Command + E.

3. Advanced Tips for Common Functions

1. Scan Multiple Disks in Parallel: In the left panel, you can click multiple disks in sequence to scan them. DaisyDisk will start an independent scanning process for each disk and manage them as tabs at the top for quick switching and comparison.
2. Focus on User Folder: For daily cleanup, directly scanning the ‘User Folder’ on the left is often more efficient than scanning the entire system disk, because it directly locates all files under your personal account (Desktop, Documents, Downloads, etc.), which are the main gathering places for user files.
3. Use ‘File List’ View to Assist Decision-Making: When browsing the sunburst chart, click the ‘List View’ button in the toolbar (or press Command + 2) to switch to the traditional file list view, sorted by size, name, etc., which is very useful for accurately comparing file sizes within the same folder.
4. Identify ‘Other’ Storage Space: DaisyDisk is a powerful tool for solving the problem of an oversized ‘Other’ category in macOS storage space. By scanning the entire disk and sorting by size, those files that do not belong to standard media, applications, or document categories (such as caches, old iOS backups, virtual machine disks, software components, etc.) will be exposed.

4. Common Problems and Solutions

1. Problem: Slow scanning speed
   • Solution: Scanning speed mainly depends on the disk type (SSD is much faster than HDD), disk used capacity, and CPU performance. Ensure that no other heavy I/O operations (such as video rendering, large file copying) are running in the background. Try closing and rescanning.
2. Problem: Unable to delete some files, prompting ‘The operation can’t be completed’
   • Solution: This is usually because you do not have the corresponding system permissions. Please ensure:
     1. The account you are currently logged into has administrator privileges for the file.
     2. Try quitting related applications first (especially software that may be occupying the file).
     3. For system core files, DaisyDisk may not be able to delete them directly due to system protection. Please operate with caution and only delete personal data files that you clearly know.
3. Problem: The chart is unclear or too small
   • Solution: Use the pinch/scroll zoom gesture on the trackpad or mouse to zoom in or out of the entire sunburst diagram view, making it easier to view small sector blocks.
4. Problem: How to analyze external hard drives or network volumes?
   • Solution: As long as the disk volume is mounted and displayed in macOS Finder, it will automatically appear in the disk list on the left side of DaisyDisk. Click it to analyze it like an internal disk.
5. Problem: Why is the scan result inconsistent with the storage space in ‘About This Mac’?
   • Solution: macOS storage space calculation includes hidden data such as system snapshots and Time Machine local snapshots. DaisyDisk analyzes the actual file occupancy at the file system level, and differences between the two are normal. DaisyDisk focuses more on showing the space occupancy of user-visible files.
6. Problem: Marked the wrong file, how to cancel?
   • Solution: In the ‘Trash’ panel, find the file you mistakenly marked, and click the ‘Remove’ button on its right (usually a cross icon) to remove it from the pending deletion list.
7. Problem: Can deleted files be recovered?
   • Solution: No. DaisyDisk’s deletion operation is permanent and directly bypasses the Trash. Once ‘Delete’ is clicked, the file will be immediately and completely removed. Therefore, before executing deletion, be sure to carefully confirm via ‘Quick Look’.
8. Problem: Does the software require administrator privileges?
   • Solution: Scanning and browsing disk information does not require special permissions. However, to delete system-protected files or files not owned by the current user, you need to enter the administrator password for authorization. Daily cleanup of personal files (such as Downloads, Desktop) does not require additional permissions.
