1. Overview

Duplicate File Finder allows you to quickly find and remove duplicates, and then organize your files and folders properly to avoid cluttering the disk space with useless data. There are four steps to remove duplicate files and folders from your Mac:

1. Scan folders or disk volume

When you launch the application, you will see the first dialog window that invites you to drag and drop the folders you want to scan. Just move individual folders to the window or click the Add Folder button to choose folders or whole disks (it supports both external and internal volumes). You can also scan your Home folder or Photos Library in one click right from this window. Then click the Scan button.

2. Preview the results

When duplicate scanning starts, an animated chart is displayed to reflect search results. The entire search process takes from one to five minutes.

After the scan is complete, Duplicate File Finder will display the Overview tab. Here you can view your duplicate files and folders. You can choose to preview the details in either a bar chart or pie chart. In addition, if you have similar folders (folders that contain a mix of duplicate and unique files), this tab provides information about their size. Cleanup Hints are an added bonus, which help make the selection of the duplicates easier and more efficient.

3. Select the duplicates

At the top of the window you will see different tabs. Click on Duplicate Files to preview duplicates within different file types (music, video, documents, etc.) There is also an All Files category, where you can preview duplicates of all file types.

Preview the files and select those you want to remove. If you have thousands of duplicates and need quick ways to select duplicates, use the Auto Select button. It will select the duplicates automatically and you will just need to preview them and confirm their removal.

4. Remove the duplicates

The last step is to delete duplicates by clicking the Review & Remove button. You will see the list of all selected duplicates. Preview them and confirm by clicking on Remove. If you want to keep some of the files, just uncheck the checkboxes by the names of the files and they will not be deleted.
