Duplicate files can accumulate on your computer over time. Too many duplicate files can take up unnecessary space and may cause confusion and disorganization. As with other versions of Microsoft Windows, Windows 11 doesn’t come with a feature or app to handle duplicate files. And it takes time and patient to get rid of them manually. The good news is that a duplicate file finder for Windows 11 can automate the process of finding and deleting duplicate files.
There are some apps that can handle duplicate files in Windows 11. They vary in features, performances, ease of use, etc. Below you can find the list of them and also my reviews.
Cisdem Duplicate Finder
Free Download Windows 11/10/8/7 
Free Download macOS 10.11 or later
Compatibility: Windows 11, 10, 8, etc., 64-bit only
Latest version: 2.9.5, released in February 2023
Our take: An easy-to-use app that automatically finds all duplicate files and lets you delete all duplicates with a single click
Cisdem Duplicate Finder is powerful and easy to use for everyone. This app identifies duplicate files by content and also provides an option to identify by name. It can find duplicate images, audios, videos, documents, archives and all other duplicate files on your Windows PC and external storage devices.
The groups of duplicate files that have been found will be displayed in the results window in the app. There are three view modes, letting you easily view duplicate files.
In each group of duplicate files, Cisdem Duplicate Finder automatically selects all files but one for deletion. This way, all duplicates are selected for you to remove at once. Or, you can choose a desired selection rule. There are multiple selection rules to help you mass select unwanted duplicates.
Compatibility: Windows 11, 10, 8.1, 8, 7, Vista, XP
Latest version: 24.30.0100, released in April 2023
Our take: A file manager that provides a basic but reliable duplicate file finder feature
XYplorer is a popular file manager for Windows. It’s powerful and feature-rich, helping users efficiently manage files, including duplicate files.
XYplorer’s duplicate finder feature is somewhat hidden. It’s not as straightforward as dedicated software. But once you know how to use it, you will find that it works well.
Access the duplicate finder feature by choosing Edit > Find Files and then clicking the Dupes tab. XYplorer allows you to detect duplicate files by hash and provides four hash algorithms (MD5, SHA-1, SHA-256 and SHA-512) for you to choose from. Any of the four algorithms can do the job.
XYplorer will display the groups of duplicate files that it has found. In each group, select the file that you don’t need and then press the Delete key. Also, there are selection rules to automate the selection and save your time.
XYplorer isn’t worth buying if you only need its duplicate finder feature. It’s a better idea to get a dedicated duplicate file finder for Windows 11.
Compatibility: Windows 11, 10, 8 and 7
Latest version: 5.19, released in March 2023
Our take: A highly customizable duplicate file finder and remover that can be overwhelming for beginners
Duplicate Cleaner, or more precisely Duplicate Cleaner Pro, is a sophisticated and highly customizable piece of software to help Windows users get rid of duplicate files.
There are four modes to scan for duplicate files on Windows PC: Regular mode, Image mode, Audio mode and Video mode. The Regular mode, which can find duplicate videos, pictures, songs and other duplicates that may exist on your computer, should be enough for most users in most cases.
There are sets of options to configure the Regular mode. If you are not that tech-savvy, you can stick to the default settings, which should work well enough for you. If you want to, you can experiment with different settings until this duplicate file finder works in the way you except.
As you can see, there are modes dedicated to handling duplicate image, duplicate audios and duplicate videos. With these modes, the settings can be complicated and overwhelming.
Compatibility: Windows 11, 8.1, 8, 7
Latest version: 10.0.0.2, released in April 2023
Our take: A basic, free duplicate file finder and cleaner
Auslogics Duplicate File Finder allows you to find all duplicate files or specific types of duplicate files (such as duplicate pictures). It identifies duplicates by content and name (or content only).
When you use Auslogics Duplicate File Finder to search a large folder for duplicates, it can take a long time. It is the slowest of all the tested duplicate file finders. In the test, it took over five minutes where others only took dozens of seconds.
By default, this app ignores system folders when searching for duplicate files, which prevents the system folders on your PC from being touched. This is especially useful when you search your entire computer for duplicate files.
Its Rescue Center feature is worth mentioning. The feature allows you to easily restore files in case of accidental deletions.
Compatibility: Windows 11, 10, 8.1, 8, 7, Vista
Latest version: 6.3.0.1
Our take: A good duplicate file finder and remover for Windows 11 once you figure out how it works
As the name tells, this app is a dedicated to find duplicate files. It has all the makings of a good duplicate file finder. But its interface can be confusing. Once you figure out how to use it, this app won’t let you down.
To get started, you need to add the folder in which you’d like to search for duplicate files. You can add a folder by either clicking the Add Folder button in the toolbar at the top or clicking the Add Folder button in the sidebar on the right. When I used this app for the first time, I thought I should start with clicking the New Project button.
Before you click the Start Scan button to scan the added folder for duplicate files, you can choose the desired scan method if needed. But the default mode may already be what you need. It can find exactly identical files regardless of name.
Once the scan is complete, you will see a list of all the duplicate files that have been found by this app. There is even a preview pane where you can easily preview a file without leaving the app. In each group of duplicate files, you can select the unwanted ones for removal, or you can let this app do this for you.
Compatibility: Windows 11, Windows 10, 8.1, 8 and 7
Latest version: 4.3.1, released in July 2022
Our take: An easy-to-use and open source duplicate file finder
dupeGuru is open source and free to use. It has three modes. The Standard mode finds duplicate files in general. The Picture mode searches for duplicate photos and certain similar photos. The Music mode searches for duplicate songs. The latter two modes provide some options to let you decide what duplicates to find.
Like Duplicate Cleaner Free, dupeGuru found 43 groups of duplicate files in the test and missed one group.
It’s a simple app with a simple interface, allowing you to easily find and remove duplicate files.

Compatibility: Windows 11,10, 8.1 and 7, 32-bit and 64-bit
Latest version: 6.10.10347, released in March 2023
Our take: A PC cleaner that comes with a basic and useful duplicate file finder tool
CCleaner is a well-known PC cleaner. It provides a Duplicate Finder tool to help users clean up duplicate files. This tool is available independently.
CCleaner’s Duplicate Finder can compare files and identify duplicates by name, size or content. To find true duplicates, make sure that you set it to do the identification by content.
CCleaner can search one or more folders for duplicate files. But it by default doesn’t search the subfolder when it searches a folder for duplicate files. As a result, it may fail to find certain duplicate files. To prevent this, you need to enable an option (which is hidden). To enable the option, you need to choose the Include tab first, click the Edit button, click the Options dropdown list and then choose the Include files and subfolders option.

There are many possible causes, such as copying and pasting of files, unnecessary backups, downloading the same files twice and importing the same photos twice. Duplicates are almost inevitable. If there are many of them on your PC, it’s a good idea to weed them out.
No. As with Windows 10 and earlier, Windows 11 itself doesn’t have a feature or app to identify and remove duplicate files. If you want, you can use Windows 11’s file manager app File Explorer to do it manually. You can also use Windows 11’s PowerShell to find duplicate files using the command line.
According to tests and reviews, Cisdem Duplicate Finder is the best app to automatically find duplicate files and mass delete them with your permission. It offers both basic and advanced features and options to meet users’ needs.
We create, copy, download and import hundreds and thousands of files, which can result in duplicate files on our computers. We want to get rid of them and get organized.
