Disk deduper

A desktop app that will help you find and deal with file duplicates on you drive

Features

• Free, Open Source without ads
• Cache support - second and further scans will be miles faster than the first one
• GUI frontend - uses QT 5 framework
• Multiple tools to use:
  • View and manage duplicates - Finds duplicates based on file name or hash
  • Automatic deduplication - You select a master folder and slave folders, it finds duplicates and moves them into a folder you specify.
  • Extension filter - Choose which extensions to white(black)list
  • Similar Images - Finds images which are not exactly the same (different resolution, watermarks)
  • File stats - Gather metadata from files (e.g. EXIF for images) and display it a nice table
