软件介绍
Doppel finds duplicates fast. Really fast. It 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.
