Duplicate Files Remover

Duplicate Files Remover finds every duplicate file on your Android phone — photos, videos, songs, PDFs and documents, downloads and more — and lets you review and delete them to free up storage space. Everything runs on your device. Nothing is uploaded, nothing is deleted without your say-so, and there are no ads.

FIND EVERY DUPLICATE, NOT JUST PHOTOS
Most duplicate cleaners only look at your gallery. Duplicate Files Remover scans all file types:
• Photos and screenshots
• Videos
• Music and audio
• PDFs and documents (DOCX, XLSX, PPTX, TXT, EPUB and more)
• Other files (APKs, ZIPs, downloads)

SCAN YOUR WHOLE PHONE, ONE CATEGORY, OR A FOLDER
• Whole-device scan: one tap checks internal storage and your SD card, including WhatsApp media folders
• By type: scan only Photos, Videos, Audio, Documents or Other files
• By folder: pick specific folders and rescan them any time

FINDS SIMILAR PHOTOS AND VIDEOS TOO
Exact-match duplicate finders miss a photo that was saved twice at different quality, or a video that was re-shared and re-compressed. The Similar Photos scan compares what the image looks like, not just its bytes, and groups look-alikes with a similarity score so you decide what stays.

MATCHES SONGS EVEN WITH DIFFERENT ALBUM ART
The same track downloaded from two places often has different cover art embedded, so ordinary duplicate finders treat them as different files. This app compares only the audio itself.

REVIEW BEFORE YOU DELETE
• Duplicates are grouped, with one copy suggested to keep — change it if you like
• Preview anything: pinch-to-zoom photos, play videos and audio, read PDFs page by page
• Nothing is pre-selected for similar photos, and nothing is removed without confirmation
• See exactly how much space you freed after every cleanup, plus your lifetime total

FAST, EVEN ON A FULL PHONE
• Files of different sizes are skipped without being read
• Large files get a quick partial check before a full comparison
• Results are remembered, so rescanning is much faster
• Scanning continues in the background, and an interrupted scan resumes where it stopped

PRIVATE BY DESIGN
• 100% on-device: your files never leave your phone
• No account, no sign-up, no internet needed
• No ads

PERMISSIONS, EXPLAINED
• Photos and videos: to show previews of your media
• All files access (optional): needed only for the whole-device scan, because Android hides documents and app media folders from ordinary media permissions. You can decline and scan chosen folders instead
• Notifications (optional): to tell you when a background scan finishes
The app cannot read Android/data or Android/obb — Android blocks every app from those folders.
