Delete Duplicate Files in Windows 11
Windows 11 offers plenty of suggestions for cleaning up the storage space. You can open Settings app and navigate to “System > Storage” section to fine all these suggestions. Under “Storage management > Cleanup recommendations” section, you can find the files already synced in cloud and delete them if not needed. Other than this, we do not see any options are available to find and delete duplicate files available in your system. The only option for you is to manually explore the files and delete them based on the names. Otherwise, you can go for third-party apps only which will make the task much easier.
Using Default Options in Windows 11
Windows 11 uses a naming convention when the duplicate files are available in the same location. For example, if you copy and paste or download a text file “my_text_file” multiple times in your “Downloads” folder then the files names will be like below:
- my_text_file – Copy
- my_text_file – Copy – Copy
- my_text_file – Copy – Copy (2)
- my_text_file – Copy – Copy (3)
You can use one of the below methods to easily find and delete the duplicate files when the file name contains “Copy”. Remember, the this works only within a folder. Otherwise, directly go to section 2 which explains finding duplicate files in entire system using third-party apps.
1.1. Find Duplicates Within a Folder Using File Explorer
Here is how you can find duplicate files using File Explorer:
- Press “Windows + E” keys to open File Explorer app.
- Navigate to the folder where from where you want to delete the duplicate files.
- Click on “Sort” from top toolbar and then select “Name” option to sort all the available files based on file names. You can also select “Ascending” or “Descending” to list down the files accordingly.
- If the files are showing as icons, click on “View” and then select “Details” option to arrange the files in details view.
- Check the file names containing “Copy” and delete them to clean up the folder.
1.2. Search and Delete Files from File Explorer

- Right-click on the file you want to delete and select “Open file location”. This will take you to the folder where the duplicate files are located. From there you can check and delete the file.
1.3. Using Command Prompt
If you have large number of file names with “- Copy” in a single folder, then manually selecting and deleting them is a tedious task. For example, you might have mistakenly pressed “Control + V” keys twice and pasted thousands of files two times in a folder. After some days, if you are surprised with the duplicates then you can use “Command Prompt” to cleanup in few seconds instead of manually scanning for duplicates.
- First, open the folder in File Explorer which contains all the duplicate files.
- Right-click on the folder and select “Copy as path” option. Alternatively, you can copy the file path from the address bar.
- Now, click the search icon or box in the task bar and type “cmd” or “command prompt”.
- Command Prompt app will show as a first result, right-click on it and select “Run as administrator” option. Remember, you can also right-click on Start menu and select “Terminal (Admin)” option. From Terminal app, you can open Command Prompt and follow the below steps.

del "* - Copy.txt"and press enter key to delete all files which contain the word “Copy” in file name. Note that if your duplicate files are in any other format like png, jpeg, or XML, then you have to replace txt with the right format.
2. Finding and Deleting Duplicates with Third-Party Apps
As you can see the default options in Windows 11 are quite impractical works in single folder. Even searching and deleting is also not a simple task if files with same names are available in multiple locations. If you are running low disk space with huge number of duplicate files scattered over the system, then try one of the below mentioned third-party apps.
2.1. Using SearchMyFiles
SearchMyFiles app helps you to locate and delete duplicate files easily and quickly. The app offers enhanced Windows search function to find the duplicate files with the same name.
