Great!! - Installed Duplicate Detector Pro. Drop the folder, scan, push two buttons and it removes the duplicate items to the trash. Easy to use and only $2! Thank you.

Version 1.81
Review by Twoloosescrew

Version 1.81 exceeds causes memory limits to be exceeded - Previous versions worked great, however after upgrading to Version 1.81, the app now consumes memory until the limits are exceeded and the system pauses the application. I’m waiting for the developer to fix this issue as this version is unusable.

Duplicate Detector Pro - Well worth the tiny amount of money to upgrade to the Pro version. I am always amazed that there are so many duplicate files everytime I run the program. Keeps my computer in much better shape!
