DaisyDisk for Mac v4.21.4 Graphical Disk Usage Display Chinese Activated Version Download

DaisyDisk is a visual disk space analysis tool designed specifically for macOS. It intuitively displays disk and folder usage through gorgeous sunburst charts, helping users quickly locate and clean up files that take up large amounts of space, thereby efficiently managing limited storage resources. Whether you are a Mac novice or a seasoned user, this tool can help you “reclaim” tens of GB of valuable space.

1. Core Interface and Workspace Detailed Explanation

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

1. Scan Target Selection Panel: Located on the initial interface or sidebar. Lists all scannable volumes (such as “Macintosh HD”) and common folders (such as “Applications”, “Users”).
2. Visual Sunburst Chart Main Workspace: Occupies the main window after scanning is complete. Displays storage usage with a multi-layered concentric sunburst chart.
   • Sectors: Each sector represents a file or folder, with area proportional to occupied space.
   • Colors: Different colors distinguish different types of files (such as applications, documents, media, etc.).
   • Hierarchy: From center to outer edge, represents the hierarchical relationship from root directory to subdirectories. Click any sector to “drill down” into its contents.
3. Path Navigation Bar and Information Panel: Located at the top and bottom of the window.
   • Path Bar: Displays the path of the currently viewed folder, supports clicking for quick navigation.
   • Information Panel: When hovering or selecting a sector, displays detailed information such as name, size, percentage, and modification date of the item.
4. Collector Panel: Located on the right side or bottom of the window (draggable). Used to temporarily store files planned for deletion, facilitating batch preview and operations.
5. Toolbar: Contains common function buttons such as “Scan”, “Show/Hide Collector”, “Quick Look”, “Show in Finder”, etc.

2. Complete Operation Flow: From Scanning to Cleaning

1. Launch and Select Scan Target

Step 1: Open the DaisyDisk application.

Step 2: In the main interface, click the disk volume you want to analyze (such as “Macintosh HD”) or a specific folder (such as “Users”).

Step 3: Click the “Scan” button in the lower right corner, or directly press the shortcut Command + R to start analysis.

2. Interpreting Analysis Results and Navigation

After scanning is complete, the sunburst chart will be generated automatically.

Operation Method:

• View Details: Hover the mouse over any sector, and the bottom information panel will display its detailed information.
• Drill Down: Click a sector (folder) to expand it and display its internal contents. You will “drill into” that folder level.
• Return to Upper Level: Click the parent folder name in the top path bar, or press the shortcut Command + [.
• Quickly Locate Large Files: The sector with the largest area in the sunburst chart is usually the largest space consumer. View from outer edge inward; the outermost ring is usually specific files.

3. File Review and Collection

Before deciding to delete files, be sure to review them first.

Operation Method:

• Preview Files: Select a file sector and press the Spacebar (macOS Quick Look) to preview the content, supporting images, documents, videos, etc.
• Locate in Finder: After selecting a sector, click the “Show in Finder” icon in the toolbar or press the shortcut Command + Shift + F, and the system will open Finder and highlight the file.
• Add to Collector: After confirming the file needs to be deleted, drag it to the “Collector” panel on the right, or select it and press the shortcut Command + Delete. This operation only adds the file to the pending deletion list, not actually deleting it.

4. Final Cleaning and Export

Step 1: Click the “Collector” button on the right side or bottom of the window to ensure it is visible.

Step 2: In the Collector panel, verify all files again. You can use the Spacebar to preview again here.

Step 3: After confirmation, click the “Delete” button at the bottom of the Collector panel.

Step 4: DaisyDisk will pop up a confirmation dialog allowing you to choose the deletion method:

• Move to Trash: Safe option, files can be recovered from Trash.
• Delete Immediately: Irrecoverable, please use with caution.

After selection, click “Delete” to complete the cleaning.

3. Advanced Tips for Common Functions

1. Multiple Scan Comparisons: DaisyDisk can save scan snapshots. After scanning is complete, save the current state via the menu bar “File” -> “Save Snapshot…”. You can reopen it later to compare disk space changes.
2. Filter Display: In the sunburst chart interface, use the menu bar “View” -> “Show Files Only” or “Show Folders Only” to simplify the view and focus on specific types of items.
3. Quick Scan of Common Locations: In addition to the main disk, the DaisyDisk initial interface usually provides quick entries such as “Users”, “Applications”, etc., allowing quick analysis of user directories or application folders with more targeted results.
4. Use Color Legend: Understanding the file types represented by sunburst chart colors (such as images, videos, applications) helps quickly identify whether a certain type of file occupies too much overall space.
5. Clean System Caches and Old Data: Focus on folders under the user library such as `~/Library/Caches`, `~/Library/Application Support`, etc. When scanning user directories, drill down into these folders to often find cache files that can be cleaned.

4. Common Problems and Solutions

1. Problem: Scanning gets stuck or is slow.
   • Solution: Scanning speed depends on disk size, number of files, and types (network drives or cloud sync folders may be slower). Try scanning specific subfolders instead of the entire disk first. Ensure DaisyDisk is updated to the latest version to fix known scan timeout issues.
2. Problem: Unable to delete certain files, prompting “Insufficient Permissions”.
   • Solution: These are usually system-protected files or files belonging to other users. DaisyDisk will prompt you. It is recommended not to force delete system files. For files belonging to other applications, try uninstalling the related application first, or use the “Show in Finder” function to view and modify their permissions in Finder.
3. Problem: The sunburst chart looks cluttered, making it difficult to distinguish small files.
   • Solution: Use the “Hide Small Files” function in the “View” menu. This merges many trivial small files into an “Other Files” sector, making large files more prominent. You can also zoom in (using pinch gesture on trackpad or holding `Command` and scrolling the mouse wheel) to view details.
4. Problem: How to analyze external hard drives or network drives?
   • Solution: Ensure the drive is properly connected to the Mac and mounted. Launch DaisyDisk, and the drive will usually appear in the initial scan target list. If it does not appear, try accessing the drive once in Finder, then restart DaisyDisk.
5. Problem: Scan results do not match actual space usage?
   • Solution: DaisyDisk calculates logical usage, while the system may include hidden files, system snapshots (Time Machine local snapshots), etc. It is recommended to restart the Mac first, then rescan. Also, ensure DaisyDisk has been granted “Full Disk Access” (set in System Preferences -> Privacy & Security).
6. Problem: What to do if important files are accidentally deleted?
   • Solution: If “Move to Trash” was selected, immediately open Trash and right-click to select “Put Back”. If “Delete Immediately” was selected, you can try using data recovery software (such as Disk Drill), but the success rate is not 100%. Therefore, we strongly recommend confirming files are backed up before cleaning.
7. Problem: DaisyDisk uses a lot of CPU resources during scanning?
   • Solution: When scanning a large number of files, high CPU usage is normal. After scanning is complete, resource usage will drop rapidly. If high usage persists, check for background process conflicts or contact official technical support.
