A high-speed duplicate detector!

Do you have duplicate files taking up precious space on your hard drive? Do you get lost in an ever repeating, ever increasing mess of files?
If the answer is “yes” to either question, Doppel is the answer.

Doppel finds duplicates fast. Really fast.

Doppel uses custom developed specialist algorithms to process hundreds of thousands of files, and terabytes of data, in seconds; and a high-speed index to reduce disc accesses and increase speed of subsequent scans.

A simple interface, that would be recognisable to any Mac user, makes Doppel easy and intuitive to use.

Straightforward automatic selection of duplicates and sets of duplicates reduce the complexity of file screening, with the option of manual screening if required. Don’t worry, Doppel issues an alert if a selection includes all copies of a file, preventing accidental deletion.
