Step-by-Step Guide to Fix the Error: “No duplicates found: The software detects no duplicate files even if they exist”

Introduction

Finding and removing duplicate files on your system can free up disk space and improve performance. However, some software may fail to identify duplicates even when you know they exist. This guide walks you through step-by-step adjustments, advanced diagnostics, and specialized tools to fix the issue.

Step 1: Check the Search Settings

Ensure the software’s search criteria are set correctly:
- File content: Recommended for exact duplicates (byte by byte).
- File names: Useful for files with identical names.
- File extensions: Select a specific file type (e.g., images .jpg, documents .docx).
- Creation or modification dates: For duplicates differing only by date.
📌 Expert Tip: If using software like AllDup, check the settings in the search tab and tick “Compare by content.” This ensures ultra-precise analysis.

Step 2: Identify the Correct Locations to Scan

Manually select the relevant hard drives or folders. Some software may skip certain locations by default.
For example:
- Explicitly add the path C:\Users\[YourUser]\Documents to ensure your personal documents are included.
- Exclude sensitive system folders like C:\Windows.

🔗 Useful Resource:MiniTool Power Data Recovery offers customizable scan modules to find duplicate files even in complex environments.

Step 3: Use Byte-by-Byte Comparison Modes

Tools like Ashisoft Duplicate File Finder allow you to compare files at the binary level. This method is optimal for duplicates identical in content but with different names or metadata.

Activate the Checksum function: This calculates a unique fingerprint for each file, ensuring highly reliable searches.

Step 4: Exclude Certain Folders or File Types

Limiting the search to relevant locations or formats (e.g., .jpg, .mp4, or .docx) reduces false positives. You can also exclude folders containing system data.

Example with AllDup:
- Go to the “Exclusion” tab.
- Add paths such as C:\Windows, C:\Program Files.

✨ Pro Tip: The less your scan is flooded with temporary or system files, the more precise your results will be.

Step 5: Preview Before Taking Action

Before deleting or moving detected files, inspect them using preview functions provided by tools like Norton Utilities or Duplicate Cleaner Free.

What to look for:
- Check the format/extension.
- Image dimensions (to avoid deleting a higher-quality version).
- Internal content, especially for .doc or .xls files.

Step 6: Create an Advanced Automated Search Script

If using Linux-based systems (or even Windows with PowerShell), a custom script can automate your search. Here’s a basic example for finding duplicates in Linux using the MD5 command:

find . -type f -exec md5sum {} + | sort | uniq -w32 -dD &gt; duplicates.txt

✏️ Replace . with the path to your desired scan location. Detected duplicates will be listed in duplicates.txt.

Step 7: Reset the Settings or Switch Software

If all steps fail, reset your software settings to their default values.
Otherwise, try an alternative! Here are some recommendations:
- MiniTool ShadowMaker: MiniTool ShadowMaker
- EaseUS Todo PCTrans: EaseUS Todo PCTrans
