Please beware of using this product and spending $ on it. I have no idea how many others were affected or corrupted by this app. Duplicate File Finder (you can find it in the Mac App Store) is the best for me, but is a paid app. My concern is that I happened to notice this because I was actively engaged with a couple of the contacts at present. Interestingly, I had to go back several days before I purchased the product in order to get a fairly correct list of my contacts, and EVEN THEN, some contacts that I knew were in my phone prior to the use of this product did not come through.

Thankfully I had backups of my phone on iCloud, and was able to restore my contacts. I wrote an email to their help department (of course they do not provide any phone number) regarding my issue and distress over paying even the small amount for the full version, and received ZERO response. The app purports to allow you to undo and changes made, but this feature did not work either. To delete junk email, open Mail and choose Mailbox > Erase. Deleting unneeded music, movies, and other media can free up a lot of space, as can deleting files in the Downloads folder. When I used this app to recognize and merge duplicate contacts, it erased many contacts completely (strangely, it seemed to target some of the people I most frequently communicate with), and for others, my texts would be labeled “Maybe: ,” even after I would go into the contact and manually correct the contact. Manually delete unneeded files by moving them to the Trash, then emptying the Trash.

My issue was that I had (obviously) duplicate listings after adding contacts from different sources- I.e. I had very high hopes for this app after reading all of the positive reviews. The app is free to operate with duplicate files, if you want to operate duplicate folders in-app purchase required. You will have found and selected duplicate files in specified folder, review selected files and Remove them. BEWARE! I would give this app a zero star if possible When scan finished, click Autoselect button.
