Two, Complete Operation Process: From Creating a Scan to Exporting Results

1. Creating/Adding Scan Tasks

Step 1: Adding Scan Paths

• Method: Click the “+” button on the top toolbar, or drag the file folder or disk directly to the left path list area of the software main window.
• Location: On the left side of the top toolbar / Above the left navigation panel.
• Shortcut: Cmd + O to open the file folder selection dialog box.

Step 2: Setting Scan Options (Optional)

• In the left “Filter” area, you can check specific file types (such as “Only Images”) or add/exclude specific file extensions (such as .psd) by clicking the “+”.
• To find similar images, you need to select the “Find Similar Images” option before scanning (usually in the filter or advanced settings).

2. Executing the Scan

Step 3: Starting the Scan

• Method: Click the “Scan” button in the central top toolbar.
• Location: Central top toolbar.
• Shortcut: Cmd + R.

Note: The results are displayed in real-time during the scan. You can pause or stop the scan at any time.

3. Reviewing and Selecting Duplicate Items

Step 4: Viewing Scan Results

• After scanning, all duplicate file groups are displayed in the main work area. By default, they are categorized by file type.
• Use the view buttons at the top of the main work area to switch between List View (for detailed information), Thumbnail View (for visual comparison, especially suitable for images), and Info View (for file properties).

Step 5: Smart Selection of Files to Delete

• Method 1 (Manual Selection): Manually uncheck the files you want to keep in each duplicate file group (at least one file must be retained in each group).
• Method 2 (Automatic Selection): Click the “Smart Selection” button in the top toolbar, which automatically marks the recommended deletion items in each duplicate group based on rules (such as “Keep the latest”, “Keep the earliest”, “Keep the shortest file name”, etc.).
• Location: Right side of the top toolbar, next to the “Scan” button.
• Use the sorting function (by name, size, date, etc.) in the main work area to make it easier to compare and make decisions.

4. Handling (Deleting) Duplicate Files

Step 6: Executing the Delete Operation

• Method: After confirming the selection, click the “Delete” button in the top toolbar.
• Location: Right side of the top toolbar.
• Shortcut: Cmd + Delete.

Step 7: Selecting the Delete Method

• After clicking the “Delete” button, a menu pops up with options:
  1. Trash: Safe option, files can be recovered.
  2. Permanently Delete: Irrecoverable, directly erases the files.

5. Completion and Review

After deletion, the software will display the total amount of freed storage space. You can close the current scan result (Cmd + W) and start a new scan task.

Three, Advanced Techniques for Common Features

• Accurate Search for Similar Images: After adding the scan path, make sure to enable the “Find Similar Images” feature in the “Filter” or “Settings” and adjust the threshold (e.g., 90%). This is very helpful for cleaning up photos taken in a single session or of different sizes.
• Protect Important Files with an Ignore List: Add system folders, project source directories, etc., to the “Ignore List” to avoid them from being accidentally scanned and deleted. Right-click on the left-hand “Ignore List” to add items.
• Batch Preview and Compare: In “Thumbnail View”, you can intuitively compare all duplicate images within a group by horizontally viewing them. Use Space key to quickly preview a single selected file.
• Export Scan Reports: Before deletion, you can export the current list of duplicate files to CSV or text files via the “File” > “Export” function in the menu bar, for archiving or further analysis.

Four, Common Issues and Solutions (FAQ)

• Issue 1: Slow Scan Speed
  • Solution: Reduce the scan scope by adding only the target folder rather than the entire disk; specify file types in the filter to reduce irrelevant file comparisons; ensure your Mac has enough memory resources.
• Issue 2: Files Deleted by Mistake
  • Solution: If you deleted files and selected “Move to Trash,” recover them immediately from your Mac’s “Trash.” It’s recommended to use the “Smart Select” feature before important operations and carefully review them, or move files to a folder for backup.
• Issue 3: Software Failed to Find Known Duplicate Files
  • Solution: Check if the file type or extension is excluded in the filter; confirm that “Find Similar Images” is enabled (if looking for similar images); try adjusting the scan mode to “Content + Filename” (check in settings).
• Issue 4: How to Scan External Hard Drives or Network Drives
  • Solution: Ensure the external device is correctly connected and mounted on your Mac, then drag it into the scan path list as you would with a local folder.
• Issue 5: Software Alerts “Unable to Access Certain Files”
  Solution: This is usually due to Mac’s privacy settings. Go to “System Preferences” > “Security & Privacy” > “Privacy” > “Full Disk Access,” and check the box for Cisdem Duplicate Finder.
• Issue 6: System Files Showed in Scan Results
  Solution: Before starting the scan, add the key directories (e.g., /Library, /System) to the “Ignore List” to avoid accidental deletion and system instability.
• Issue 7: Software Interface is Partially Unreadable or Showing Characters Incorrectly
  Solution: Try resetting the interface language or font in “Preferences.” If ineffective, reinstall the software and ensure the downloaded version is compatible with your macOS version. Refer to Apple’s official developer documentation for macOS 10.15 and above, which has stricter requirements for application sandboxing.
• Issue 8: How to Determine if “Smart Select” Rules Are Appropriate?
  Solution: First, use “Smart Select” to mark items, then manually check a few groups of duplicate files to confirm the rules (e.g., “Keep the latest”). If unsatisfactory, you can revoke the selection and manually adjust them.
• Issue 9: Does the Software Support Batch Processing of Multiple Folders?
  Solution: Fully supported. You can drag multiple folders or disks into the scan path list at once, and the software will scan and find all duplicate files under these paths. This greatly improves the efficiency of cleaning up.
• Issue 10: How to Confirm How Much Space Was Freed After Deletion?
  Solution: After the deletion operation, the software will pop up a summary window, clearly showing the total amount of storage space freed. You can also view the space to be freed in the “Summary of Duplicate File Information” area in real-time.

Five, Quick Key Summary Table (Mac Version)

Six、 Case Study: Release 10GB of Photo Library Space

A photographer friend of mine once faced iCloud photo library synchronization issues, resulting in thousands of duplicate and extremely similar photos stored locally. We used Cisdem Duplicate Finder to resolve this issue.

Steps:

1. Add Path: Drag the “Photos” application’s original photo files folder (typically located at ~/Pictures/Photos Library.photoslibrary) into the software.
2. Set Filter: In the “Filter” section, only check the “Image” type and enable “Find Similar Images,” setting the similarity threshold to 95%.
3. Run Scan: Click “Scan,” and the software takes about 15 minutes to analyze over 20,000 photos.
4. Review Results: The scan results show over 500 groups of duplicate/similar photos, occupying approximately 12GB of space. We used the “Thumbnail View” to quickly browse and confirm that most were indeed duplicate shots or backups from editing processes.
5. Smart Selection: Use the “Smart Selection” feature, with the rule set to “Keep the largest file size” (usually the original file), then manually adjust a few groups.
6. Delete and Confirm: Select “Move to Trash” to delete. This ultimately freed up 10.2GB of valuable hard disk space, without losing any critical original files.

This case fully demonstrates the software’s professional capabilities in handling large volumes of similar images. Its “Find Similar Images” feature is a must-have for photography enthusiasts or designers. According to reviews by reputable publications such as Macworld, tools based on content hashing algorithms outperform simple file name comparisons in terms of accuracy.
