Two, Complete Operation Flow: From Scan to Delete

Step 1: Create/ Add Scan Projects

Method A: Drag and Add Drag and drop the Finder’s file or disk icons directly to the central area of the software’s main window.

Method B: Add via Button Click the + button in the top toolbar, select the folders or disks to be scanned in the pop-up window, and then click “Open”.

Method C: Scan Recent Locations Click the dropdown arrow next to the “Add” button to quickly select from the “Recent Folders” list.

Step 2: Configure Scan Options (Optional)

Before clicking the “Scan” button, you can configure settings in the “Options” section at the bottom of the interface:

• Minimum File Size: Ignore files smaller than the specified size to speed up the scan.
• Exclude List: Add specific files, folders, or extensions to exclude from the scan.
• Find Similar Photos (Pro version feature): Check this option to find visually similar but differently named photos.

Step 3: Execute Scan

Click the “Scan” button in the top toolbar, or use the shortcut Command + R to start the scan. The scan can be interrupted at any time by clicking the “Stop” button.

Step 4: View and Select Duplicates

After the scan is completed, all duplicates will be grouped together.

1. Browse Results: Use the filter in the left sidebar by type to view, or sort (click the column header) to arrange the duplicates in the main list.
2. Preview Files: Click a selected file to preview it using Space key.
3. Select Files to Delete:
   • Manual Selection: Manually select files to delete in each duplicate group (usually, it is recommended to keep one copy).
   • Automatic Selection: Use preset rules in the top “Select” menu.
     • Smart Selection: Automatically retain one file in each duplicate group (usually based on the latest modification date or path priority).
     • Select Duplicate Files in a Specific Folder (Pro version feature): Batch-select all duplicate copies within a specific folder.
     • Reverse Selection: Use the “Keep Files…” feature to quickly select files to keep, then reverse-select the rest.

Step 5: Safely Delete Duplicates

1. Review and Confirm: Review and confirm the number and size of selected items in the bottom status bar. Be cautious and ensure that the necessary files are retained.

Three, Advanced Techniques for Common Features

1. Efficiently Handle Large Numbers of Duplicate Items

• Use the “Copy Files by Type” view to focus on cleaning up the largest space-consuming media files (such as videos).
• Create and save an “Automatic Selection Rule””, such as always keeping files in the “Downloads” folder, or always deleting duplicate items in the “Cache” folder.

2. Merge Similar Folders (Pro Edition)

This feature is used to consolidate two files that contain a large amount of overlapping content. In the scan results, if you find two folders with similar structures and many duplicate files, you can use the “Merge Folders” feature to merge the contents of the two folders into a single folder, deleting the duplicates and avoiding the hassle of manual organization.

3. Use History Records to Restore Files

If you accidentally delete a file, do not empty the Trash. You can immediately enter the software’s “History Records” view to find the corresponding deletion record and use the “Restore” feature to return the file to its original location. Even if the Trash has been emptied, the Pro version may still be able to restore the file if you check the history.

4. Scan Network Drives and External Hard Drives

Ensure the drive is mounted on your Mac, then drag the target folder into the software as you would add a local folder. This is useful for organizing backups on a network drive or NAS.

Four, Common Issues and Solutions

Issue 1: Slow Scan Speed

Solution：

• Set a “Minimum File Size” in the scan options to ignore irrelevant small files.
• Add paths such as the system temporary directory and application packages (`.app`) to the “Skip List”.
• Do not scan the entire system disk (Macintosh HD) at once; prioritize scanning the user folders (such as “Downloads”, “Documents”, “Desktop”).

Issue 2: Uncertain Which Duplicate File to Delete

Solution：

• Make use of the “Quick View” (press the spacebar) to preview file contents.
• Check the “Path” column to usually keep files in the common project folders (such as “Documents”) and delete copies from temporary or download directories.
• Use the “Smart Select” feature, which automatically makes choices based on preset rules (such as keeping the file with the latest modification date), and let you decide the final choice.

Issue 3: Software Reports “Similar Photos” but Looks Different

Solution：The “Similar Photos” search is based on image content analysis and may find photos that are similar in composition or taken in the same scene. Before deleting, make sure to preview and confirm each file individually. You can adjust the sensitivity of the “Similar Photos” search (if the software provides this setting) or use it as a reference, ultimately deciding by hand.

Issue 4: How to Scan Hidden Duplicate Files?

Solution：Duplicate File Finder Pro by default scans most visible files. To scan hidden files (such as files starting with a dot), first display hidden files in Finder by pressing the shortcut Command + Shift + ., then drag the target folder into the software. The software will recognize and scan these files.

Issue 5: Does the Software Support Scanning iCloud Drive Duplicate Files?

Solution：It fully supports. Simply navigate to the iCloud Drive folder in Finder and drag the iCloud Drive folder into the software window when adding a scan location. Note that scanning iCloud Drive may take a long time, depending on the number of files and the network synchronization status.

Issue 6: After Deleting Duplicate Files, Does the Disk Space Not Release Immediately?

Solution：If you selected “Move to Trash”, the files are only moved to the Trash and not truly deleted. You need to manually empty the Trash to release the space. Alternatively, you can choose the “Permanently Delete” option when deleting, and the space will be released immediately.

Issue 7: What If the Software Crashes During Scanning?

Solution：First, ensure your Mac system version meets the software requirements. Then, try restarting the software and reducing the scanning scope, such as scanning a single folder instead of the entire disk. If the problem persists, you can try uninstalling and reinstalling the software, or contact our support team for assistance.

Issue 8: How to Backup My Scan Settings and Selection Rules?

Solution：In the software’s preferences (Preferences), there is usually an option to “Import/Export Settings”. You can export custom skip lists, automatic selection rules, and other settings as a configuration file, making it convenient to import and use on other Macs, or quickly restore after reinstalling the system.

Five, Summary of Mac Shortcuts

Six、Practical Case: Cleaning Download Folder

Many users’ “Downloads” folder accumulates a large number of duplicate files, such as PDF manuals downloaded from different websites or screenshots saved repeatedly. Below is a practical case of using this software to clean the “Downloads” folder.

First, open the software and drag the “Downloads” folder from Finder to the main window of the software. Then, in the “Options” section, set the “Minimum File Size” to 10KB to ignore those irrelevant small cache files. Click the “Scan” button next.

After the scan is completed, in the filter on the left sidebar, you can view the results by file type. For example, if you find a large number of duplicate .dmg installation packages, you can click “Select” menu under “Choose Duplicate Items” and specify the path to clean. The software will automatically select all duplicate .dmg installation package copies in the “Downloads” folder and retain only one.

Finally, click the “Delete” button, choose “Trash”, and confirm. Afterward, manually empty the trash, and you will release a large amount of disk space. The entire process takes less than two minutes, which is very efficient. This technique is also applicable to the daily maintenance of the “Desktop” and “Documents” folders.

Seven、Summary and Suggestions

Duplicate File Finder Pro for Mac is a reliable tool for disk space management. With its powerful scanning capabilities and intelligent selection logic, users can easily identify and clean those files occupying valuable storage space. Both ordinary users and professionals can benefit from it.

It is recommended that users develop the habit of regularly scanning, such as once a month. At the same time, be sure to carefully preview and confirm before deleting files, and make full use of the “Smart Selection” and “Move to Trash” features to ensure data security. For users unfamiliar with the system, it is recommended to only scan personal folders to avoid any accidental operations affecting the system stability.
