There's a new Duplicate Cleaner coming!

From the upcoming version 3.0, Duplicate Cleaner will be splitting into two editions: Duplicate Cleaner Free and Duplicate Cleaner Pro.
Duplicate Cleaner 3 Free will still have all the power of the earlier versions, and won't have any restrictions or limits - it still does more than similar non-free programs.  The new Pro version builds upon Duplicate Cleaner to add a host of exciting new features, including similar image finding,  a duplicate folder view, zip file scanning, finding shared duplicates between archives, and more.

The new website is www.duplicatecleaner.com, where you can find more details on the upcoming release.
