Find Duplicate Files on your Mac With Gemini: The Duplicate Finder from MacPaw

Published April 8, 2012 - 2 Comments

I knew that I had duplicates.  I save things all the time, and then I make backups.. and backups of those backups!  I have external hard drives with backups.  I have a wireless NAS drive with backsups.  I have a SugarSync account that does automatic online backups.  Then of course there’s my Dropbox. So there’s no shortage of backups.  The problem is that those backups are not organized in any logical way, so they’re really more useless than anything.  I probably couldn’t find what I was looking for if I needed to, yet my backups continue to get larger every time, simply be virtue of backing up what’s already been backed up.  It’s insane.  So yeah.. I knew that I had duplicate files within those backups.  I just didn’t know HOW BAD it really was… until I bought a neat little program from the Mac App Store called Gemini: The Duplicate Finder by MacPaw.

If you’re a Windows user… well.. I’m sorry… but this isn’t for you.  Do yourself a favour, and throw your Windows machine in the garbage.  Then go buy a Mac.  You will thank me later.  I promise.

Gemini: The Duplicate Finder is $7.99; it’s not expensive, but it’s also outside the range of “Bah.. It’s only a buck.. I’ll try it, what’s the worst that can happen?  I waste a whole dollar…”.  And quite honestly, I think that too many of the $0.99 Apps flooding the Mac App Store are crap, so I’m willing to spend a little more for something that does the job I’m looking for, and does it well.  Reading through the reviews I quickly noticed one thing… most people who purchased Gemini loved it!  There were a couple of people who said that it did not work at all, and that kind of worried me, but there’s always someone out there who runs into problem.  It doesn’t matter what it is.

I am pleased to tell you that (so far) I am one of the very happy users of Gemini: The Duplicate Finder!  As I started the post with… I knew that I had duplicates.  I just didn’t know HOW MANY…  Well so far I have scanned a 250 GB external harddrive and discovered 61 GB worth of duplicate files!  I have some MP3s backed up SEVEN TIMES!  I think that every music video I’ve ever purchased is duplicated 2 or 4 times… and this is just ONE hard drive… I can’t wait until I scan the 1.5 TB NAS.  That’ll be scary.

Of course finding the duplicates is only the beginning.  If you don’t do anything with them, then what’s the point of even looking for them?  Gemini: The Duplicate Finder makes it very simple to delete the duplicate files, while at the same time providing checkpoints to ensure that you don’t inadvertently wipe out more than you intended to.

I am going to play with it some more, and you can be sure to see a complete review in the near future.
