About Decloner
An easy-to-use utility to find and eliminate duplicate files on your Mac. Decloner uses a reliable secure hash algorithm (SHA-1) to determine if files are identical. It has a convenient and easy-to-use interface, and can quickly process large number of files on internal or external disks. Decloner lists duplicate files and lets you delete them either one by one, or mark several files and delete them all at once. You can inspect files and view their contents using Leopard’s QuickLook feature.

Decloner never deletes files permanently. Instead, it moves files into the Trash so that you can always restore them if you change your mind. Decloner supports file name exclusion lists and setting minimum file size to ignore small files. Sparkle auto-update feature is included for your convenience.
