Want to know how to find duplicate files on Windows 11?

Duplicate files can be pretty annoying, even if organizing things is not your cup of tea. Not only do they unnecessarily take up space in your computer, but they also overload the drive, reduce computer performance, and make searching through data quite strenuous. That said, it becomes vital to get rid of them.

These unwanted files can come into existence in a variety of ways. More often, they are a result of merging folders or drives, storing backups, or simply copying files from one location to another. Manually looking for them can be very time-consuming.

This is why it’s preferable to have an automated tool do the job for you. There are many of those tools available but be wary of ones that locate the duplicate files solely based on the file name. The best duplicate file finder tool will compare additional properties, including the file size and type.

So let’s look at how these tools can help you out!

1. Use Windows Explorer To Find Duplicate Files on Windows 11.

Microsoft doesn’t provide a separate software you can use to find duplicate files on your computer easily. Despite this fact, it does offer certain features to get yourself organized, which you can utilize to locate similar files based on their name.

This method is especially useful if you’re low on space and don’t want to download and install extra apps.

Here’s how you do it:

  1. First, click on Windows Explorer and go to the folder that has the target files.
  2. Now, you will see a Sort menu on the toolbar. Click on the drop-down symbol next to it.
  3. Then, you will come across a list of options you can organize these files. Click on Name, Size, or Type for more convenience.

From there, compare the files and delete the ones you find duplicated.

2. Use Command Prompt To Delete Duplicate Files on Windows 11.

By default, Windows will have a suffix -Copy at the end of files that are duplicates. They also contain a number representing how many times that file has been copied. This helps in finding them using the sort feature explained above.

However, if there are a number of copies, deleting these may seem like a never-ending task. Fortunately, you can make it easier for yourself by using the Command Prompt.

These are the steps you’ll need to follow:

  1. Begin by clicking on the Start button at the bottom-left corner of the screen and type cmd in the search box.
  2. Then, click Run as administrator

If the file name includes a number at the end or has a different file extension, change the command accordingly.
