Duplicate Files Remover

Overview

Struggling with low storage and cluttered files? Duplicate files are a silent storage killer. From repeated downloads to backed-up WhatsApp media, your Android device may be carrying gigabytes of unnecessary duplicates. The solution? Smart duplicate file remover apps that actually work.

After testing several apps for speed, accuracy, and safety, here’s our curated 2025-tested list.

Top Duplicate File Remover Apps for Android

1. Files by Google

   
   

   Rating: ★★★★★

   
   

   Why It Stands Out: Files by Google isn’t just a file manager—it’s a powerful cleaner too. The app has a built-in duplicate file remover that scans for identical images, videos, documents, and audio.

Key Features:

• Fast and lightweight

• Clean and ad-free interface

• Smart suggestions to clean junk and duplicate files

• Completely free

Test Result: Found and safely removed 500MB+ of duplicate media without false positives.

2.  CCleaner – Cleaner App by Piriform

   
   

   Rating: ★★★★☆

   
   

   Why It Stands Out: CCleaner by Piriform is a well-known name in PC cleanup, and its Android version brings the same reliability. It excels in removing junk files, temporary cache, APKs, and duplicate files—all with minimal user input.

   
   

Key Features:

• Smart scan for junk, cache, and residual files

• Built-in duplicate file remover

• App manager and storage analyzer

• Option to schedule regular cleanups

Test Result: Removed over 850MB of junk and duplicate files during testing. Interface is clean, with minimal ads and helpful prompts for first-time users.

3. Remo Duplicate File Remover

   
   

   Rating: ★★★★☆

   
   

   Why It Stands Out: Remo’s app is great for identifying duplicates using file attributes like name, size, and content. It’s especially good for cleaning camera roll duplicates.

Key Features:

• Photo preview before deletion

• Audio, video, docs supported

• Intuitive UI

Test Result: Cleared 400MB+ in duplicate images, particularly helpful in gallery cleanup.

4. Duplicate Files Fixer

   
   

   Rating: ★★★★☆

   
   

   Why It Stands Out: A comprehensive tool with advanced filters, though the free version contains ads and limits some features.

Key Features:

• Custom scanning by file type

• Clean reports and previews

• Cloud duplicate scanning (premium)

Test Result: Detected 1GB+ duplicates but required manual selection to avoid important file deletion.

5. Nox Cleaner – Smart Storage Optimizer

   
   

   Rating: ★★★★☆

   
   

   Why It Stands Out: Though primarily known as a phone booster, Nox Cleaner’s duplicate cleaner tool is surprisingly effective.

Key Features:

• Automatic cache and duplicate cleaner

• Scheduled scans

Test Result: Removed 600MB of duplicates alongside junk files in one go.
