How to Remove Duplicate Files in Windows 11

This guide will walk you through the steps to identify and remove duplicate files on your Windows 11 computer. By following these steps, you’ll be able to clear out unnecessary files and improve your system’s performance.

Step 1: Download and Install a Duplicate File Finder Tool

The first step is to download a reliable duplicate file finder tool.

There are many free and paid options available online. Choose one that has good reviews and fits your needs. Some popular options include CCleaner, Duplicate Cleaner, and SearchMyFiles.

Step 2: Launch the Duplicate File Finder Tool

Once you’ve installed the tool, open it to start the process.

Most duplicate file finder tools have an easy-to-navigate interface. Familiarize yourself with the basic layout and options available in the tool you’ve chosen.

Step 3: Select the Folders to Scan

Select the folders or drives you want to scan for duplicate files.

It’s usually a good idea to start with common folders like Documents, Pictures, or Downloads. This is where duplicates tend to pile up the most.

Step 4: Customize the Scan Settings

Adjust the scan settings according to your preferences.

Many tools allow you to filter by file type, date, or size. Customizing these settings can help narrow down the search and make the process faster.

Step 5: Run the Scan

Initiate the scan to let the tool search for duplicate files.

This step might take a few minutes or longer, depending on the size of the folders or drives you’re scanning. Be patient and let the tool do its magic.

Step 6: Review the Results

Once the scan is complete, review the list of duplicate files.

Most tools will provide a preview of the files so you can see which ones are duplicates. Be sure to double-check the files before proceeding.

Step 7: Delete the Duplicate Files

Select the duplicate files you want to delete and confirm the deletion.

Many tools offer an option to move files to the Recycle Bin or a specific folder before permanently deleting them. This gives you an extra layer of security in case you accidentally delete something important.

After completing these steps, your computer should be free of duplicate files, giving you more storage space and potentially improving performance.
