DupInOut Duplicate Finder helps you reclaim your lost storage by deleting duplicate files and other digital junk accumulated over years of your computer usage. DupInOut helps you find duplicate documents, images, music, videos, archives and more. DupInOut has a simple Drag & Drop interface which you can use to quickly add folders to the Search List and Ignore List. By default, DupInOut searches all files, irrespective of their types, for duplication. However, you can change it by selecting only fewer file types that you want to scan. You can also use the optional File Size Filters to exclude files above/ below a certain size. Once the duplicate scan is completed, DupInOut will show a comprehensive report with a pie-chart to help you understand the amount of storage occupied by each file type group. DupInOut has an in-house file preview feature so that you don't have to open each file while reviewing. DupInOut lets you mark hundreds of duplicate files automatically with One-Click using a pattern of your choice (Newest files in each group, oldest files in each group, Mark files by their name, size, path, creation date, hash, etc). Finally, you can delete the duplicates permanently, move them to another folder, or add prefix/ suffix and rename the files. You can also import/ export your scan preferences to easily get started in future without needing to define the entire list of Search & Ignore Folders List or set up File Size & File Type Filters again.
