Duplicate File Finder: Cleaner

Get back gigabytes of space from duplicate files, without the guesswork.

Duplicate File Cleaner finds files that are exact copies of each other in the folders and drives you choose: documents, downloads, music, videos, archives, installers and photos. You see every copy side by side, one copy of each file is always kept, and the extras go to the Trash in one click.

On the Mac App Store since 2015, with more than 150 five-star reviews from customers around the world.

NEW IN 2.1: A FRESH, SIMPLER DESIGN
• Three clear steps: choose, scan, review
• See how much space you can free before you remove anything
• Every copy shows Keep or Trash, so you always know what happens
• Filter by documents, music, videos, archives and more
• Keep the oldest or newest copy of each file with one click
• Beautiful in light and dark mode, built for Apple silicon and Intel Macs

EXACT MATCHES ONLY
• Files are compared byte by byte, so only true duplicates are shown
• Files with the same name but different content are never matched
• Identical folders are found too, so a whole duplicate backup can go in one step

SAFE BY DESIGN
• One copy of every file is always kept
• Duplicates go to the Trash, so you can put them back
• Each file is checked again right before it's removed, and anything that changed since the scan is left alone
• Photos and Music libraries and apps are never touched
• Your files never leave your Mac: no account, no uploads, no tracking

EASY
• Drag in folders, external drives or files, or pick Downloads, Documents or Desktop
• Reveal any copy in Finder before you decide
• Skip small files or file types you don't care about in Settings
