Impressive! - I am very particular about apps I download - ESPECIALLY those related to file manipulation such as deleting, moving, etc. After downloading Duplicate Detective, I performed a test to verify the app truly uses a hash-based alogorithm to detect duplicates. Comfortable with my findings, and assuring I had a current backup, I did my entire harddrive on my macbook pro. 15 minutes later, after scanning through 127,000 files (267GB worth of data), 950 files, equating to 4GB, was cleared up (I usually avoid keeping duplicates as much as possible, so wasn’t too surpised of the small results). Not only did the app do an excellent job, as advertised, but added little things like messages informing me it was still working, it hs not crashed, and “So, how is your day going” added a friendly and helpful user interface. Kudos to the developer(s) of this app. (As a side note, I saw in someone’s review that when dragging a folder over to Duplicate Detective, the folder was just deleted. I replicated that by dragging and dropping “Pictures”, located on the Favorites Panel in Finder. I Dragged it over - and the white cloud appeared -poof gone. The actual folder nor any files were delete, of course, since items on the favorites panel are just a pointer to the actual folder.)

Review by macmanmk

Worthless since Yosemite install - How many people know the term "shill"? One needs only look at the bulk of the reviews for this application to realize the developer is padding their rating. Nearly all the reviewers leaving glowing remarks have reviews of but a single application...this one. And if someone steps forward and says the product doesn’t work as advertised, they are rewarded with multiple thumbs down for their honesty. Well thumb me down all you want…this software is garbage. This app has crashed five times in a row now since the Yosemite upgrade. Avoid purchasing until the developer fixes the critical bugs.

Generally good, noticed one (minor) bug - Like past reviewers have said, it tends to take a while to scan a folder. I had to leave it running overnight to get it to finish its scan. But the scan seems to get all the duplicate files and will group them by folder if all the contained files are the same (which is a really nice feature). One bug that should be fixed in future versions: On the results page when you are selecting the files that you want to delete, the estimated size that will be made available isn’t accurate. You can recreate this bug by just toggling the checkboxes on a few items and seeing how the estimated size jumps around. For me, toggling a ~10MB file results in the estimated size jumping around by over 100GB. My scan found 100s of GBs of duplicates so I don’t know if this bug just presents itself for really big scans or it shows up in smaller scans too. The bug doesn’t really affect how well the app does its job of removing duplicates but it would be nice to have an accurate estimate of how much space would be saved.

Review by Yor B

I bought, I used, I liked, It works - Duplicate detective does what it says it can do. It works quickly, is selective driven by me. I can write more but the stars say it all. 4926 - 5 stars against 188 do not like stars. I read some of the do not likes. It seems they might just need to read the help or possibly ask for help, and don’t delete without looking at the file if you are concerned.

Good Stuff Except…. - Love this company and all of it’s apps. The thing that DRIVES ME NUTS is that they constantly want me to rate the app before I use it. Over and over again. Stop it please!
