How to Remove Duplicate Files in Windows 11: A Step-by-Step Guide

Duplicate files can take up unnecessary space on your computer and make it harder to organize your files. Removing them helps free up storage and improves system efficiency. Windows 11 does not include a built-in tool to find duplicate files, but you can still remove duplicates easily with a few simple methods.

This guide will walk you through basic, clear steps to identify and delete duplicate files on your Windows 11 PC. Whether you prefer using built-in tools or third-party software, these instructions will help you clean up your files safely.

By following these steps, you can reclaim disk space and keep your files better organized. The process is straightforward, even if you are not very tech-savvy.

Let’s get started with some quick notes to prepare you for the process.

Quick Note Before You Begin

  • Backup Important Files: Always create a backup of your important data before deleting any files. This prevents accidental loss.
  • Check File Locations: Know which folders you want to scan for duplicates (e.g., Documents, Pictures, Downloads).
  • Close Other Programs: Close any programs that might be using files to avoid conflicts during scanning or deletion.
  • Administrator Access: Make sure you have administrator rights on your Windows 11 PC for smooth operation of some tools.

Step 1: Manually Search and Delete Duplicate Files

If you only have a few duplicate files or want to start small, manual deletion can work well. This is the safest method but can take more time.

  1. Open File Explorer: Click on the folder icon in the taskbar or press Windows + E to open File Explorer.
  2. Navigate to the Folder: Go to the folder where you suspect duplicates exist, such as Documents or Downloads.
  3. Sort Files by Name or Date: Click on the “Name” or “Date modified” column header to group similar files together. This helps spot duplicates.
  4. Look for Duplicate Names: Check for files with the same name or very similar names.
  5. Compare File Sizes: Right-click a file and select Properties to check its size. Duplicate files often have the same size.
  6. Open and Verify: Double-click files to open and confirm if they are identical before deleting.
  7. Delete Unwanted Duplicates: Select the duplicate file, right-click it, and choose Delete. Files will go to the Recycle Bin first, allowing recovery if needed.

This manual method is effective for small numbers of duplicates but not practical for large collections.

Step 2: Use the Windows Search Tool to Find Duplicate Files

Windows Search can help locate files with the same name or type, making it easier to find duplicates.

  1. Open File Explorer: Press Windows + E.
  2. Search for Specific File Types: Type *.jpg or *.docx in the search bar to view all files of that type.
  3. Sort the Results: Click on the “Name” or “Size” column to group files that might be duplicates.
  4. Review and Delete: Check files as in Step 1 and delete duplicates.

This method is slightly faster but still requires manual checking.

Step 3: Use Third-Party Duplicate File Finder Tools

For faster and more thorough results, using dedicated software is recommended. These tools scan your PC to identify exact duplicate files automatically.

Popular Free Duplicate File Finders

  • CCleaner: Known for cleaning junk files, it also includes a duplicate finder.
  • Duplicate Cleaner Free: A user-friendly tool designed specifically for finding and removing duplicate files.
  • Auslogics Duplicate File Finder: Free tool with a simple interface and effective scanning.

How to Use a Duplicate File Finder

  1. Download and Install: Go to the official website of the chosen tool and download the free version.
  2. Run the Program: Open the software with administrator privileges.
  3. Select Folders to Scan: Choose the folders you want to check for duplicates.
  4. Start the Scan: Click the scan button to begin. The tool will compare files based on name, size, and content.
  5. Review Results Carefully: The program will list duplicate files. Review the list to ensure you do not delete any important files.
  6. Delete Selected Files: Use the tool’s delete function to remove duplicates safely. Some tools offer to move files to the Recycle Bin or a backup folder first.

Using these tools saves time and reduces errors compared to manual methods.

Alternative Method: Using PowerShell to Find Duplicate Files

For users comfortable with command-line tools, PowerShell can help identify duplicate files by comparing file hashes.

Get-ChildItem -Path "C:YourFolder" -Recurse | 
  Get-FileHash | 
  Group-Object -Property Hash | 
  Where-Object { $_.Count -gt 1 } | 
  ForEach-Object { $_.Group | Select-Object -ExpandProperty Path }

This command scans the specified folder recursively, calculates file hashes, and groups files with identical hashes (duplicates). It then lists their paths.

Important: Be cautious when deleting files using PowerShell commands. Always verify duplicates manually or back up files first.
