User Experiences with diskDedupe

"The new interface in diskDedupe 2.0 makes it so much easier to see exactly what files are duplicates. I can even export the list to CSV and inspect details in Numbers. I love being able to see how many duplicates I have in specific categories - cleaned up my archives in minutes and saved 200 GB!"

"diskDedupe cleaned up my archives of Logic Pro files - where many contain the same sound files, samples, etc. It shrunk my 800 GB archive folder down to 300 GB! Now I don’t have to worry about which versions to keep: I can keep them all."
