Duplicate Photos Fixer Pro is a smart duplicate photo cleaner designed specifically for macOS. Using advanced algorithms, it can not only identify exact duplicates but also find visually similar photos based on user-defined matching levels, helping users efficiently manage their photo library and free up valuable disk space. This article provides a detailed practical guide, from core interface analysis to the complete workflow.

1. Core Interface and Workspace Overview

After launching the software, you will see a clean and intuitive main interface, mainly divided into the following functional areas:

  1. Top Toolbar: Contains core action buttons such as “Add Folder”, “Start Scan”, and “Delete Selected”.
  2. Left Source Selection Panel: Used to add image sources to scan. You can add local folders, external drives, Mac Photos library, or even connect to Google Drive.
  3. Central Preview and Results Area: After scanning, all detected duplicate or similar photos are displayed here in “groups”. Each group is arranged horizontally, clearly showing the similarity relationships.
  4. Right Settings and Filter Panel:
    • Matching Level Slider: The core control for adjusting the similarity threshold. Slide from left (loose) to right (strict) to regroup results in real time.
    • Scan Settings: Options to ignore small images, scan subfolders, etc.
    • Auto-Selection Rules: Set rules for automatically marking photos to delete, such as “Keep Newest”, “Keep Highest Resolution”, etc.
  5. Bottom Status Bar: Displays scan progress, number of duplicate groups found, and space that can be freed.

2. Complete Workflow: From Scan to Delete

Step 1: Create/Open Project – Add Scan Source

The software starts in a new project state. You need to specify the scan scope.

  • Method: Click the + Add Folder button in the left panel, or drag and drop a folder from Finder directly into the software interface.
  • Location: Left source selection panel.
  • Shortcut: Command + O to open the folder selection dialog.
Tip: You can add multiple folders from different locations (e.g., the “Pictures” directory, a “Backup” folder on an external drive) for a comprehensive scan.
Step 2: Configure Scan Parameters

Adjust settings according to your needs before starting the scan.

  • Matching Level: For first-time use, it is recommended to place the slider in the middle. It can still be adjusted dynamically after scanning.
  • Scan Settings: In the right panel, check options such as “Include Subfolders” and “Ignore Small Images (e.g., thumbnails)”.
  • Auto-Marking Rules: In the “Auto Select” dropdown menu on the right panel, pre-select a deletion rule, such as “Mark all photos except the newest in each group”.
Step 3: Execute Scan
  • Method: Click the Start Scan button in the top toolbar.
  • Location: Center of the top toolbar.
  • Shortcut: Command + R.

During scanning, the bottom status bar shows progress. Scan speed depends on the number and size of images.

Step 4: Review and Select Duplicates

After scanning, all duplicate groups are listed in the central area.

  1. Browse Groups: Use the mouse wheel or trackpad to scroll up and down through all duplicate groups.
  2. Preview Images: Hover the mouse over any image to enlarge it. Click an image to view a larger preview at the bottom or in a pop-up window.
  3. Select Images to Delete:
    • Manual Selection: Click the checkbox in the upper-right corner of each image to uncheck the ones you want to keep.
    • Apply Auto Rules: If set in Step 2, the software will mark automatically. You can also click the Auto Mark button (magic wand icon) in the top toolbar to reapply the rules.
    • Quick Select All: Above each group, there are usually quick options for “Select All” or “Invert Selection”.
  4. Adjust Matching Level: If the grouping seems unreasonable, drag the slider on the right to refresh results in real time.
Step 5: Safely Delete Duplicate Photos

This is the most critical step. Please carefully confirm your selections.

  • Method: After confirming all images to delete are checked, click the Delete Selected button in the top toolbar.
  • Location: Right side of the top toolbar (usually a red trash can icon).
  • Shortcut: Command + Delete.

After clicking, the software will pop up a confirmation dialog with the following deletion options:

  • Move to Trash (Recommended): Moves files to the system Trash, giving you a final chance to recover.
  • Delete Permanently: Erases directly from disk, unrecoverable.
Warning: Before performing a permanent deletion, it is strongly recommended to choose “Move to Trash” first and double-check in the system Trash before emptying it.
Step 6: Export/Finish

The main task of Duplicate Photos Fixer Pro is cleaning, and it does not involve traditional “project export”. After completing deletions:

  • You can close the software, or click New Scan (left side of the top toolbar) to start another cleaning task.
  • The software may generate a simple cleaning report showing the amount of space freed.

3. Advanced Tips for Common Features

  1. Precisely Control Matching Level: For professional photographers scanning burst photos, first set the matching level high (strict) to find only nearly identical copies; then lower it (loose) to find photos with similar composition but different exposure for more refined filtering.
  2. Combine Source Locations: Scan both the “Downloads” folder and the “Photos” library simultaneously to find copies that have been imported into the library but whose original files are still scattered.
  3. Use “Quick Look” for Comparison: During review, do not rely solely on thumbnails. Use the built-in enlarged preview to carefully compare image details, especially for highly similar photos, to avoid accidental deletion.
  4. Process Large Libraries in Batches: If your photo library is very large (over tens of thousands of images), it is recommended to scan folder by folder multiple times to avoid excessively long single scans and for easier management.

4. FAQ

Issue Possible Cause Solution
No duplicates found after scanning 1. Matching level is set too high (too strict).
2. The added source folders indeed contain no duplicate photos.
3. “Include Subfolders” is not checked.		 1. Drag the matching level slider to the right to lower the matching requirement.
2. Try adding a folder known to contain duplicate photos for testing.
3. Ensure “Include Subfolders” is checked in scan settings.
Software groups clearly different photos together Matching level is set too low (too loose). Drag the matching level slider to the right to increase matching precision. This is the software’s most core adjustment feature.
“File in use” or permission error when deleting photos 1. Photos are open in another app (e.g., Photos app).
2. Current user does not have write permission for the files.		 1. Close all applications that may be using these photos, especially the Photos app.
2. Ensure you have administrator permissions for the target folder. You can try copying photos to another folder with permissions for cleaning.
Scanning Google Drive is slow or fails 1. Unstable network connection.
2. Large number of files in Google Drive cloud.		 1. Ensure a stable network.
2. Consider syncing important photo folders from Google Drive to your local Mac first, then scanning the local copies for faster speed and no network dependency.
Software unexpectedly quits 1. Temporary conflict with macOS version or other software.
2. Scanned file paths are extremely deep or contain special characters.		 1. Restart your Mac and ensure Duplicate Photos Fixer Pro is updated to the latest version supporting your current macOS.
2. Try scanning folders with simpler paths and standard file naming.
