Very very helpful. You will crave more.
Bottom line - use this app. It is great. Once you use it, you may find something you wish it could do to make your elimination of duplicates easier.
So, I think there could be an easier way to do some tasks if I could sort the duplicates by file. For example, I compared my download file (which really bloated on me) to my Google Drive. The results showd me all the individual file and folder duplicates within the Google Drive itself, within the download folder and betweeen GD and Downloads. But, what I really want is to see what duplicates are just in the download folder that I have already saved to various files. Then, I can eliminate those download files and folders, allowing me to then properly save or delete the balance of downloads. We receive so many attachments or web content that goes to downloads. Plus, when using google docs, office 365 online and other shared online toos, we have to upload, download files that often travel through Downloads folder. Maybe I am missing some buried feature here - but it seemed to me that sorting the duplicates by folder might get me what I want - a global list of duplicates in the Download folder compared to the global list of drives and folders I want to compare them to.
I dropped a Raid array on it with about 1.1 million files, and it completed indexing in a reasonable amount of time (15 minutes or so). I have folders and files in one area, and then 'backup' folders of the files, but older and not in sync. Using the app 'Similar', it displayed the two folders. Example: REACH folder in two places. The dialog shows the path to each folder and duplicate and unique files. So... I want to merge the two, delete the duplicates, move the unique files, and then delete the 'source' folder. Nope. And, in the merge CONFIRM spec there is no path info, so I'm not sure which folder is which. It also seems to REVERSE the folder display from the original merge spec. Confusing. I also found I needed to display both folders first so I could manually delete the source folder, which is SLOW at best. It can't be done from the 'Similar' action because once the merge happens it indexes to the next 'similar' folder. I believe the app could be tweaked to do what I want, but for now it's a deal breaker. Of course, maybe it can do that now and I just couldn't find it. The merge options dialog doesn't offer what I want as far as I could tell from experimenting.

Thank you for the feedback.
Now we are finishing the next update with dramatically updated Merge Folders feature. The update will be available at App Store in 6 weeks.
Contact us via firstname.lastname@example.org if you are interested to get the beta of update earlier.
P.S. All your comments are accepted, and new Merge provides better experience, really close to the thing you asked.

AVOID! This software will delete NON-Duplicate files!!
I can't even begin to describe how dissapointed I am with this software! I have had this software delete NON-DUPLICATE files multiple times now, and this is while using the slower full scale option. This should be totally impossible since the developers claim the program is doing a byte by byte comparsion. I am doing a huge archival process of many harddrives and have been using this program throughout - looking back at other copies of the data I have found it deleted a series of photos that were taken in a row on a tripod, but had different files names. They were similar but NOT the same and it marked them all as duplicates and were for deleted. I also had it delete audio outputs from protools - the files were output at the same time and the same size but had diffferent audio tracks on them and it marked them as duplicates. If it was doing a real full scale scan it would not have made this mistake. Bottom line is if you are using this for photos or audio you CAN NOT TRUST this software to safely clean your computer.

The application compares files by their content byte to byte. There is a double-check for duplicates when files removed.
