GrupaDupa was created by people like you who want their hard disks free of duplicated files without spending ages in front of a computer. After extensive search and testing of available duplicate detection software we decided to write our own with emphasis on speed and ease of use -- and thus GrupaDupa was born. We dicovered that most of our duplicated files were named the same and stored more than once in different folders. We decided to optimize GrupaDupa to find those files quickly and without having to set up any preferences. This is therefore our default search.
GrupaDupa will find duplicates in any available volume in a flash. This includes hard disks, both internal and external, and any volume on your local network or on the internet. For example, GrupaDupa scanned the entire contents of one of WordPower's hard drives (126,963,803 files), filtered out all the files that were contained in folders like bundles, themes. packages etc but appeared as files, sorted them and listed 6,658 possible duplicated files. This operation took only 45 seconds to complete.
When GrupaDupa is run, it scans the requested location and presents you with a list of the possible duplicates it has found. From this list you can inspect the details of each of them, including its location, size, modification date, and checksum. You can also work with a duplicate right from our interface by opening it with its associated application, revealing it in the Finder, viewing it using Quick Look, or deleting it. A small job well done.
