Disk Diet for Mac v5.4.5 Free Up Disk Space Chinese Activated Version Download

Disk Diet for Mac is a professional disk space cleaning and optimization tool. It intelligently scans deep system areas, application caches, log files, language packs, and other easily overlooked items that take up a lot of space, helping users quickly locate and safely free up disk space. Its core design philosophy combines “one-click” operation with deep control, suitable for both ordinary users seeking efficiency and advanced users needing fine management.

I. Core Interface and Workspace Detailed Explanation

After launching Disk Diet, the main interface is usually divided into the following clear functional areas:

1. Top Toolbar: Contains core operation buttons such as “Scan”, “Clean”, “Preferences”, and “Help”.
2. Left Navigation Panel: Displays cleanable item categories in a tree list or category icon format. Common categories include:
   • System Junk: System caches, user logs, temporary files.
   • Application Junk: Caches and support files generated by various apps.
   • Large & Old Files: Files filtered by size and last access time.
   • Multi-language Files: Resource files in applications for non-system languages.
   • Developer Files: Xcode derived data, old iOS device backups, etc.
3. Central Content/Details Area: When a category on the left is selected, this area displays the specific items scanned under that category. Each item usually includes: file/folder name, size, type, last access date, and a checkbox (to select whether to clean).
4. Bottom Status Bar/Information Panel:
   • Displays the total size of currently selected items.
   • Displays used/available space of the entire disk.
   • “Clean Now” button and the estimated total space that can be freed.

II. Complete Operation Flow: From Scanning to Cleaning

1. Launch and Initial Scan

Operation: Launch the Disk Diet application. The software usually selects all recommended cleaning categories by default and automatically starts a quick scan.

Location: The center of the main interface displays the scan progress bar and the items being analyzed.

Shortcut: After launch, press Command + R to manually trigger a re-scan.

2. View and Analyze Scan Results

Operation: After scanning is complete, the size of space that can be freed is displayed next to each category on the left. Click any category to view specific files in the central details area.

Method:

1. Carefully browse the list. You can click the “magnifying glass” icon to the right of a file (or press Command + Y) to locate the file in Finder and confirm whether it can be deleted.
2. Use the filter or sort functions at the top of the details area (e.g., sort by size or date) to quickly locate the largest or oldest files.

3. Customize Selection of Items to Clean

Operation: Not all scanned items need to be cleaned. You need to manually check or uncheck them.

Method:

• Select/Deselect all in a category: Click the checkbox before the category name.
• Select individual items: Click the checkbox before a specific file.
• Batch selection: Hold Shift or Command and click multiple items, then check or uncheck them together.

4. Execute Cleaning Operation

Operation: After confirming the selection is correct, execute cleaning.

Location: Click the prominent “Clean [number] GB” button at the bottom of the interface.

Method: After clicking, the software will pop up a final confirmation dialog listing the types and total number of items to be deleted. After confirmation, the cleaning process begins. Some files may require administrator password authorization.

Shortcut: When the confirmation dialog appears, you can usually press Enter to confirm cleaning.

5. Completion and Verification

Operation: After cleaning is complete, the status bar displays the total amount of space freed. You can observe whether the available disk space shown at the bottom has increased.

Method: It is recommended to click the “Scan” button again (or press Command + R) to refresh the interface and confirm that the cleaned items have disappeared.

III. Advanced Tips for Common Functions

1. Create Custom Cleaning Rules: In “Preferences”, you can add specific folders or file types to ignore, preventing them from being scanned and accidentally deleted.
2. Deep Scan “Other” Space: When the “Other” category in macOS “About This Mac” storage management takes up too much space, you can use Disk Diet’s “Developer Files” or “Deep Scan” function (if available) to find and clean old virtual machine images, disk image fragments, etc.
3. Scheduled Tasks: Advanced versions may support scheduled tasks. You can configure automatic scanning and cleaning of specific categories weekly or monthly in settings.
4. Use “Large File Finder”: Focus on the “Large & Old Files” category and use its powerful filters (e.g., “larger than 100MB”, “not accessed for over 1 year”) to systematically archive or delete bloated media files and downloads.

VI. Practical Cases and Usage Tips

Case 1: Slimming Down “Other” Space

Many Mac users find that the “Other” category in “About This Mac – Storage” takes up an astonishing amount. Using Disk Diet, you can specifically select the “Developer Files” category to clean Xcode’s DerivedData, old iOS backups, etc. These files are usually huge and no longer needed, effectively recovering tens of GB of space.

Case 2: Cleaning Large Media Files

After long-term use, the Downloads folder or Desktop may accumulate a large number of expired videos and DMG installers. Using Disk Diet’s “Large & Old Files” function, set filters to “larger than 500MB” and “not accessed for over 6 months” to quickly locate these “space killers” and clean them with one click.

Tip: Use Scheduled Tasks to Keep the System Clean

For users pursuing long-term system smoothness, you can enable scheduled tasks in Disk Diet’s settings. Set automatic cleaning of system caches and log files every Monday at midnight, which keeps disk space sufficient without manual operation each time, saving time and effort.

Through the above detailed interface analysis, step-by-step guide, and tips summary, you can fully master the usage of Disk Diet for Mac, thereby efficiently and safely managing your Mac disk space and keeping the system running smoothly.
