This is a nice program that can hardly be criticized for the work it does - but there is something missing which would make the program SO much more useful: replacing files with aliases, rather then deleting them.
I don't know about other people's workflow, but on my computer duplicate files are in certain folders for a reason. I don't want to simply delete them from there, because, for example, they belong to the project in that folder. But copies of the same files also belong to other projects in other folders. So, technically speaking, those are "duplicate" files. In principle I'd need only one copy of the file, but it makes no sense for me to delete the other copies either. It should be very simple to implement a feature to replace all duplicates with aliases. Then I can select one "master copy", and the files in the project folders would only be links/aliases to that master.

This problem should could be solved if Apple introduced a new file system such as ZFS instead of HFS. ZFS supports deduplication by default which means it's transparent to the user which is so awesome.

I absolutely agree with Frankof: replacng with aliases (or even better: symlinks) is really missing. And I don't get it why, it's so obvious! It's like copy without past or ying without yang

TidyUp has the functionality of replacing with symlink or alias and has an active promo at the moment.

I tried it. Looks ok for my first try. Cool interface.

I wish the devs would remove those corny jokey things that appear during scanning. Humor is such a subjective thing. The dev imposing their own sense of humor can be irritating or at least unwanted. It's just corny.

Does this only delete files, or will it replace duplicates with hard links? There are times, I'd rather do the latter.

I have no problem paying for an app that works, but this app doesn't give you much of an option, It selects the files and rather than a delete button there an activate (buy) button.

I've been paying shareware fees for over 30 years and this type of nonsense is insulting.

I don't understand. You mean to tell us you paid $9.99 and was asked again to pay?
If you think that Gemini would work fine and you try out the app in demo mode, then what's the bother if it doesn't work full on during the demo period?

You should evaluate the app itself and how it works rather than your dissatisfaction with the licensing/demo. Which is very suitable for comments instead.

If you can't evaluate it, then don't. You're doing the readers of Macupdate a disservice writing uninformed "reviews".

I don't consider this an "uninformed review" at all. It's pretty straightforward: He can't properly evaluate the software because they've hobbled the demo.

You know what's nonsense? Bagging on users who "can't evaluate" software when the dev makes it impossible to properly evaluate it. THAT'S nonsense.

I pay for software I use. If it’s a demo then it should be a timed demo so I can evaluate the full functionality. I really have no qualms about spending money on software that will make my life easier. After the brief and disappointing ’test’ of this software, I couldn’t tell if it looked at file names or file contents. The developer’s demo decision also provided me with clues as to how much the developer valued users.

A lot of the software I use is shareware, all paid for, and I even donate to freeware developers. A demo like this is so insulting that it gets deleted immediately.

Apple's App stores are killing the idea of shareware and causing the creation of one-trick-pony apps. You either pay a cheap price for software you can't fully evaluate, go to a site like MU and get a functional copy or timed demo to evaluate. A crippled demo isn't worth evaluating, especially if only does one thing.

I agree with you 100%, Mark3785. My reply was to Mikael B, who I think is being unnecessarily aggressive and out of line.

I just wasted an hour on the Gemini Duplicate Finder only to discover there's a brick wall at the end of the scan and I'd have to pony up money to "evaluate it further." WTH? This after watching it DEVOUR 8 GB of RAM during the scan until my computer was almost locked up. Due to that restriction there's no way I could make a judgment to whether the program was competent or not. I have no idea what the developers are thinking but this went right in the trash.

In the end I had much better luck with the Araxis Find Duplicate Files program (which I bought) and even the fairware, DupeGuru. Basically, this crippled Gemini demo cost them the sale.

@Mark3785, don't try and evaluate apps — as in grade them — when you can't run them in full mode. Comment away all you want, but if you grade it you better have either run it properly in full mode for a time or you had good reasons to expect to run on your platform.

You grading the full app now because the demo doesn't work the way you want it is tantamount to someone giving a half star because an app for OS X 10.6 and later doesn't run on OS X 10.5. It's a whine piece, not an enlightening and honest review.

While developers decide how a demo should work that is not what you grade in an app. You grade its functions and performance. Also it's not MAS tactics we grade but the app themselves.

@Evatar, you last comment does illustrate, perhaps inadvertently, what I think is the proper way to address the situation that you're discontent with a demo, a lack of demo, or whatever it is that's preventing a proper review:

You comment what you have a problem with, clearly describe how you arrived at your conclusion (the background), give some alternatives you've found and finally you don't skew the grading by giving a grade on something you haven't properly evaluated.

That's informative, helpful and fair to everyone. That's all I can hope for from the members at Macupdate.

It's a rainy day so I decided to go through my Pictures folder and organize things a bit. I realized that I had uploaded a lot of duplicates from my camera so I went to ACDsee's Duplicates Finder. I selected my Pictures folder and it didn't respond after about 20 seconds. Had to force quit several times. Gave up. Came to MU and searched for "duplicate finder" and found Gemini. I went to the MAS and bought it* and gave it a whirl after reading reviews here. After my frustration with ACDsee, this app just worked. One trick pony, yes, but it did for me what I was looking for, and did it fast.

It searches through the folder you designate and brings up a window showing each instance of each duplicate (with a preview), giving you the chance to review and select which one(s) to delete. This is important in my case as they were in different folders and have different filenames.

*I really wish that those who don't like dealing with the MAS address their concerns with developers and not vent your frustrations here on MacUpdate or give poor ratings based on that criterion.

Two minuses: Must purchase from Mac App Store, and no Snow Leopard version. Stupid Macpaw.

They must have taken your comment to heart (or similar comments), because you can now buy this app directly from their website. I got an email with a $3.00 discount to buy from the App Store, but I would rather pay the full $9.99 and buy directly from the developer. I just want to say for about the 150th time that I do not like the Mac App Store.

If you have tens of thousands of media files, like photographers and musicians can get after a year of working (and being rather sloppy) then it's a very nice one of a trick.

Some of us create and know this feeling and think 10 bucks is so worth it.

Well don't I feel like an arsehole. If I could delete my comment I would.
