How to Delete Duplicate Files by Size, Name, or Content on Windows 11

Step 1. Download and Install Wise Duplicate Finder

You can get Wise Duplicate Finder from here. Then open it directly.

Step 2. Select Locations to Scan

Click the Home tab, then select Wizard option to go on. Tap on Add folder button to select the folders or drives that you want to scan for duplicates. You can select your whole computer or specific user folders (like Documents, Pictures, Music).

Step3. Select the File type

Wise Duplicate Finder lists various file types in the File type area, which helps you save scanning time and find the target duplicates quickly.

Step 4. Choose Your Scan Mode

Wise Duplicate Finder gives you three comparison modes to find duplicate files:

• Find Duplicates by Name and Size:

Useful for quickly spotting exact file matches—works great for pictures, documents, or music files that might have been copied in error.

• Find Duplicates by Part:

This mode scans the actual file data, ensuring that only files with the same size and matching partial contents are found.

• Find Duplicates by Entire Content:

This mode will consider duplicates only if their contents are the same, which can precisely find the duplicates without any false positives.

Step 5. Start Scanning

Click the Scan button. Wise Duplicate Finder will analyze your chosen folders and list all detected duplicate files.

Step 6. Review and Manage Duplicate Files

The duplicates will be grouped, making it easy to compare them. Use the checkboxes to select which files you want to delete. After you’ve checked your selection, you can choose to move files to the Recycle Bin or backup them to somewhere you desire from the Options tab, so you can restore them if needed. Then, click the Delete Selected button.
