Are there any Open Source apps for finding and deleting duplicate files? - eviltoast

Hi Android Community, I previously used “DFCleaner” which was a free, ad-supported app that searched specified folders for duplicate files and let you preview and delete anything that it found. This app now bothers me with a consent form for ad tracking so I’ve ditched it in protest. Are there any open source alternatives to this app? I’ve tried looking in F-Droid but couldn’t find anything relevant.
