Arquivos duplicados is a free Android app developed by Lucky Luciano, which helps you find and remove all types of duplicate files from your phone. Whether it's identical or similar photos, videos, audios, .apks, pdfs, and anything else that's duplicated, this app can identify and detect them all with just one click. You can remove them individually or in bulk.

The app identifies all duplicate files present in both internal and external storage (SD card), and groups them to allow quick decisions and single-click removal. It also supports searching the entire phone, including the external SD card, for duplicate files.

In version 2.7, the app added features like deleting duplicate contacts, empty folders, system junk, residual files, cache files, and temporary files. While the app may take some time to identify duplicates if you have a large number of files, it ultimately fulfills its function.
