Find all duplicates. Fast.

A fast and easy to use tool to find and remove duplicate files. Files are automatically compared byte by byte to determine if two given files are true duplicates. Intelligent deleting can operate on all files inside a folder that exist outside of it or vice versa.


Release Notes:

- result table is navigable with the cursor keys when QuickLook is open
- removed /home and /net paths from the "Choose places to Search" table

Wonderful Utility - Simple, powerful, and does what it says. A must-have tool for cleaning up a disorganized filesystem.

WARNING, STANDARD SEARCH DOESNT DISTINGUISH THE DUPLICATES AND WILL ERASE YOUR DATA! - This Application trashed my music files and left my system with huge problems throughout the entire drive. I plan to request a refund because it did not relieve any problems or add to my systems overall performance. In fact, it was the root of serious concern and caused a factory reset and reinstallation of any files I was fortunate enough to have backed up.

Review by ajbdtc826

Not convenient at all - It looks like a well-built app for someone with a lot of time to invest in this but for a normal user, this app is very inconvenient to use. I keep getting errors that I don’t have authorization to delete certain things (not system files, rather PDFs I have on my desktop, etc). If this app was only a buck, I’d understand but for $15, no I don’t have the time for games. To charge such a price, I expected to get what I asked right upfront, not having to figure out this overly-simplistic UI that just doesn’t do what I need. Or if it does, it does a good job of hiding these options.

Not Compatible with OS X Sierra - I used this app for years and was well pleased, but when I upgraded my OS X to Sierra, Chipmunk stopped working. One feature I found most useful was the ability to delete all duplicates found within a given folder. I have yet to find another app with this ability. Hopefully the author will soon update this app so that it is compatible with Sierra.

Great for finding mass duplicates - I upgraded my review from 4 stars to 5 because this app deserves a higher average. Being able to mass delete duplicates is a godsend.

Review by The Hungry Ghost

Greate tool! - This a great tool to find duplicates of files. The developer understands all the complexities and subtleties of duplicate files. This makes for a simple and easy to use app. A couple of wish list items: And although there's a great mechanism to filter files before you start, I'd like to be able to mark certain files to ignore (just per run of a comparison), that way items that I've decided should stay can go away and not clutter up my view while I try to find problem duplicate. Thanks!

Review by BitchyMe

Not working - Just installed today on macOS Sierra 10.12.3 (16D32) but it does not appear in the application folder unless yoiu do a search for it. Nevertheless, it cannot be launch as there is a cross bar on the icon requesting to install 1.5.4 version. And this is the one what I downloaded. Just waste of time. I understand now why it is free now. At least I saved $15 for something which does not work. The App Store should get rid of this application which has been last updated in 2012 and which is not anymore comptible with Apple recent OS.
