How to Find and Delete Duplicate Files on Windows PC

Duplicate files could be a common cause if your Windows computer slows down or runs out of storage, especially when you are not sure what’s eating up all that hard disk space. Duplicate files are identical copies of the same file that are kept in different places on your laptop or computer. Examples of duplicate files include repeated photos, multiple downloads, or additional backups, which may consume valuable storage and slow down your PC.

Here in this tutorial, we will learn how to find and delete duplicate files in Windows 11/10 using a duplicate file remover tool.

Why You Should Remove Duplicate Files from Your PC

Honestly, are duplicate files seriously a problem? Here’s the reality:

• They consume valuable storage: Redundant copies of files, mostly media files like videos and photos, use up precious disk space by the gigabyte.
• They cause confusion: Have you ever edited a file only to realize that you just changed the wrong version? Having numerous copies complicates the matter of organization.
• They slow down file searches and syncing: The presence of duplicate files makes your system less efficient and more time-consuming to use.(say, OneDrive or backup tools).

If you want your computer to stay clean and organized, getting rid of duplicate files is definitely something you should do.

How to Find Duplicate Files in Windows 11/10 Manually (Not Recommended)

Before proceeding further and using any tool, you can also try to search for duplicate files manually. This tiresome method does work in certain situations, namely, on small directories or singles. But it is not efficient or dependable.

You can try finding duplicates in Windows 11/10 in the following manner:

Step 1: Sort Files by Name, Size, or Date

• Now open the folder you suspect has other duplicate files in it (Downloads, Pictures, or Documents).
• Click on Sort by shown on the top panel and select Name.
• This sorts files in a list by name, which makes it easier to see duplicate names.
• You may also sort by Size or Date Modified to detect same-name types.

Step 2: Preview Pane in File Explorer (Optional)

If you’re still in doubt that the two files are duplicates, you can choose to use the Preview Pane in File Explorer:

• Go to View > Preview Pane.
• By double-clicking a file at any given time, it also opens the preview pane on the right-hand side of the screen.

This will assist you in comparing documents, photographs, or PDFs physically before deleting something.

Step 3: Side-by-Side Compare File Details

To double-check even further:

• Right-click on the File and Select Properties.
• Compare the Size, Last Modified Date, and Location for each file.
• Do this on suspected duplicates to verify if they truly match.

This is okay if you have to navigate only a few files. But for an enormous library, this is too much.

Step 4: Use Windows Search Filters

You can search for any kind of files by just searching for it in the search option, like .jpg or .docx:

• Open the File Explorer and click in the search box on the top right of the page.
• Use filters like:1. *.jpg to see all JPEG images
  2. size:>100MB to search for large files
  3. date: last month to sift dates

• Sort by Name or Size again after loading to find duplicates.

Shortfall: This method will not find duplicate content within variously named files.

Manual Detection Limitations

These methods may be helpful for elementary sorting, but have major weaknesses:

• Time-consuming: You will have to open each file and compare it.
• Risky: There is a great risk of wrongly opening a file and deleting it.
• Missed duplicates: Files with similar content but non-similar names will be skipped.
• No auto-select: You are unable to mass-select safe duplicates with definitive certainty.
