1. Your data is important, so please be sure to read and understand the cautions in the ‘Using Araxis Find Duplicate Files’ topic in the online help before you delete any files.

2. If you have any questions about Araxis Find Duplicate Files, or if you require support, please contact Araxis using the support link in the Mac App Store.

3. If you are prompted for a serial number when you run Araxis Find Duplicate Files, you are probably inadvertently running a version of the application downloaded from the Araxis website, and not the version you have bought from the Mac App Store. To resolve this, quit Araxis Find Duplicate Files, delete all the copies of Araxis Find Duplicate Files from your machine, and then re-install from the Mac App Store.

4. Note that Araxis Find Duplicate Files only considers files to be duplicates if the file content is completely identical. Thus, for example, audio or image files with differing metadata would not be considered to be duplicates.

5. If you encounter problems deleting files using Araxis Find Duplicate Files, check that your disk volume does not have errors. To do this, run Applications > Utilities > Disk Utility, select your disk volume, and choose the ‘First Aid’ tab. Then click the ‘Verify Disk’ button.

Very good and easy and fast

Works almost perfectly for finding duplicates in my photo library and photo archive. It was fast and easy to figure out. Very clear feedback on what I am doing when manipulating duplicates. The Open in Finder option allowed me to rename files in place, which I do a lot.

I would give it five stars with one small improvement: After quickly identifying duplicates, I tried to eliminate some of them one at a time by using "Move Selected To…" to a new folder that I created. But each time I clicked "Move…" the folder reset to the Desktop. I want it to remember my last selected folder, so I don't have to navigate there from the desktop each time (I now just use Delete Selected instead, because Move is cumbersome). Also, it would be awesome to have "File Kinds" be able to *exclude* certain file types like .DS_STORE (should be exlucded by default!), or anything else I choose.

Thanks for a great little app, and for keeping it affordable.

Needs updating & no Photos capability

Had Araxis Find Duplicate Files (FDF) for several years and found it to be an excellent program that did what is was supposed to do. It was my go-to duplicate file finder. Lost the program when I changed computers; my fault when I did not check if all programs successfully migrated.

Bought it again, today, to find duplicate files in 5 Photos libraries. Unfortunately, FDF does not work with Photos. Checking that the last update was February 2013, now I understand why. The write-up on FDF in the App Store makes no mention of the inability to handle Photos libraries. This needs to be mentioned. I will keep the program because it is excellent at finding all types of duplicate files.

From past experience, I would give this program 5 stars, but will mark down 1 star for no Photos capability and another star for no recent updates.

Best I Ever Used

I keep about 7TB of data on my home network. It didn't get there overnight. I have probably put together and taken apart a dozen machines over the past 6 years, recovered disk crashes, backed up and moved stuff between machines. Typically, I hear funny noises and copy a user's stuff ASAP onto a machine I trust. As you can guess it generates lots of duplcate. Music, pictures and documents.

Araxis is the best deduplicator I've ever used. It's fast, it's accurate and huge numbers don't daunt it. Just this weekend I dumped about 800GB from two different external hard drives ino a new 3TB drive. On one those drives, there were 250,000 files. FDF found 130,000 duplicates. Didn’t hiccup. Just blew through the whole thing.
