All computers accumulate duplicate files and folders over time. You might save multiple copies of the same document, download an identical file or archive several times, or save the same email attachment in more than one location.

Duplicate Detector solves the problem by scanning your system for duplicates and allowing you to remove those unwanted files quickly and easily.

• Drag and drop folders onto the scan selection window
• At-a-glance summary of wasted hard drive space
• Quick Look preview of any file before removal
• Double check and confirm deletion

• The fastest duplicate detection algorithm available
• Intelligent sorting by greatest disk space wasted
• One click to auto-select unwanted duplicates
• Unwanted files and folders are moved safely to the Trash

• Customizable auto-selection behaviour
• Preserve specified file types and folders
• Tweak performance by setting minimum file size to scan
• Scan multiple hard drives or network volumes

Duplicate Detector’s industry-leading ultra fast and accurate scanning algorithm makes finding and removing your duplicates a breeze. Easily delete those files, free disk space, and speed up your computer today!

Duplicate Detector is a free download, fully functional for your top ten duplicates so you can judge for yourself how easy and efficient it is to use. If you prefer the ability to clean all duplicates at once, the full version is unlocked through a low cost In-App Purchase.

HUGE Help with Managing My Google Drive - This app is exactly what I needed to organize the messiest part of my life: my Google Drive (as long as you have Google Drive installed on your Mac). See I love using Google Drive to store junk that I kinda want to hang onto, but don’t want taking up space on my computer. The thing I can’t stand about Google Drive is the layout/interface, so therefor nothing ever gets organized and there are duplicates hanging out all over the place taking up my precious cloud space. The simple and clean interface of Duplicate Detector thankfully made finding my unorganized duplicate files a piece of cake. The app showed me previews of said duplicates and allowed me to choose which duplicate I wanted to delete (nice feature for piece of mind).

Crashes every time - Not worth the money in it’s current form. Has the capability to be great if they can sort out the crashing issue.

Worst - Deleted (to the trash) the only copy of several files then promptly crashed. I can’t use put-back because its not an option so now I have 1100 files in the trash that I have to figure out what subdirectory they were originally in.

Crashed after a few days; now refuses to work. - I’m so frustrated with this app. I’ve been using it to try to de-duplicate a ton of confusing, nested photo folders in what used to be iPhoto and is now Photo Library (?), and after three days of intermittent use, it’s now just sunk into inoperability, and won’t recognize any folders, any files, nothing. It “sees” no files to inspect at all. I’ve tried every fix I can think of, and nothing works — this is just one big dead lump of software. Awesome.

DUPLICATE DETECTOR - This App is absolutely fabulous. it does exactly what is says it will do, and it does it quickly behind the scenes as well, and it is automatic. it fiund 305 mb of duplicate photos in my 27” MAC and freed up this space for me. i use this app all the time whenever i sense that i’ve got several duplicate photos, i would definitely recommend this app and definitely use it all the time. Thank you Apple and Eccentric Apps for such a terrific workable app.

It actually costs $0.99. - It only clears 10 files for free. You have to pay for it to do a complete job. I’d rather they were upfront about that.
