Feature 1: Find duplicate files

Important note: Duplicate Sweeper for Windows and Duplicate Sweeper for Mac are basically the same when it comes to features and performance. However, there are some differences in regard to the interface and certain options. The Mac version has obviously fewer options. For Mac users, if this app is not useful enough, there are better alternatives to consider.

This duplicate file finder works with PC, Mac and even external storage devices such as an external drive. There are up to three ways to add folders to search for duplicates. One way is to drag and drop a folder.

The time it takes to search depends on the amount of files in the added folder(s). According to our test, Duplicate Sweeper is slow when compared to similar commercial software.

To customize a duplicate search and make the process more efficient, you can configure settings in Preferences before performing a search.

  • Search Options Under this tab, you can set the app to skip files that are larger or smaller than the specified size. For example, if your purpose is to remove large duplicates so as to free up space, you can skip small files and reduce the search time. You can also tell the app to only look for one type of duplicates such as duplicate MP3 files.search options
  • Exclude File Types Likewise, you can exclude specific types of files from the duplicate search. For instance, you can exclude system files, which can help prevent important files from being accidentally deleted.exclude file types

Feature 2: View and preview duplicates

Once the search is finished, you can view the search results and preview the duplicate files found.

In the File Types panel on the left, you can find six tabs. Under the All tab are all the duplicates that have been discovered.

In the Duplicate Groups panel, there is a list of duplicate groups. You can expand a group by selecting it. And then you can find the duplicates in this group displayed in the bottom right part of the interface.

In the preview window, you can preview audios, videos, images and documents. It’s convenient. The preview feature is especially important when you handle duplicate photos.

Feature 3: Remove duplicates

Now it's time to select duplicate files for deletion. To select a file, you can check the Remove checkbox next to a file. It will be time-consuming and tedious if you do it all manually. To make things easy and quick, Duplicate Sweeper can automatically mass select duplicates based on your preference.

From the menu bar at the top, select Duplicates. There are two rules for you to choose from: Keep Newest Files and Keep Oldest Files. If you choose Keep Oldest Files, then, in each group, all the files except for the oldest one will be selected for removal.

Once all the unwanted duplicate files are selected, you can click Recycle Selected Duplicates to get rid of them. Before the removal takes place, you will be asked to confirm it.
