The interface could use improvements to be able to select first or last duplicate for selected files. Otherwise the interface is very simple but still functional and elegant. It has lots of detail like asking if you are really sure when selecting all of the duplicates for some files. Best of all, no installer it's just a single binary!

I agree with everything that has already been written. Top marks to the programmer

DoubleKiller is a wonderfully useful piece of software that every person should have and people as disorganized as me will think is a godsend! DoubleKiller should be in everyone's System Tools alongside Disk Cleanup and Disk Defragmenter. It did an excellent job in weeding through thousands of duplicate saved photo files that Id accumulated over several years. Works with large disks (300 GBytes) too. A big `Thank You` to the author!

Quick to download; neat, clean, fairly intuitive interface; customizable but default settings were good enough for me - though was brave enough to select folders to scan without putting my tin hat on ... Used once, cautiously, and retrieved nearly a gigabyte of wasted space. No glitches.

It did more than I expected and did it very quickly. I wanted a program that would allow me to sort out duplicates for mp3 files which I seemed to have saved and backed up all over the place. I then wanted to put all the remaining files in the one main directory. I was very pleased the way this program allowed me to do the first part of the task. It also allowed me to move the files, but not quite so gracefully. I started using it for other things and pretty soon I had saved a gigabyte of space. A great program.

I ve been using DoubleKiller for a few weeks and it s fast, easy to use, and has great options. Searches can be limited to specific file types, and you have a choice to either delete the "doubles" or move them wherever you want. After it scans the directories you choose, it presents an easy-to-understand listing of all duplicate + files. I don t mind having 2 copies of something important, but 5 copies of the same .wav file @ 51MB apiece is a bit much. It s freed up over 2GBs of space on one drive alone, and no freezes or hangups while it scans. Thanks to the author for a great program!
