We must confess, we are speed-aholics... We are forever looking to squeeze every ounce of performance out of our applications. When designing our duplicate file finder Doppelganger, we researched long and hard for the fastest way to do this. Once we discovered the optimal search and display algorithms, we set about coding this algorithm in the tightest, most efficient code possible.
The chart below shows that our efforts were an overwhelming success! Doppelganger's duplicate file finder is nearly without peer!
The results above are for our software FolderMatch from which Doppelganger was taken.
Other popular duplicate file finders are not listed because they crashed or the results were totally incorrect or the performance too slow to even make this chart.
