Gemini 2: The Duplicate Finder for PC and Mac

Software Reviews and Criticism

  Great at finding duplicates and similars!

  I just got rid of over 30G of duplicate files, some of which have been floating around for a decade or more. I found the interface fairly easy to use (though at times got a little mixed up and had to remind myself to select the one I want to DELETE, not KEEP!) It’s great at identifying duplicates… but don’t expect it to be 100% spot on. I did have to make some manual changes after the scan, and that did take a little time, but far LESS time than making a manual comparison to all files scattered across three hard drives. I would recommend always, ALWAYS, visually inspecting all matches before deleting. One thing I wish it would do, for when it finds duplicates scattered between two folders, is remember which folder you kept them in (much like it remembers whether you prefer older or newer, higher or lower resolution (or bitrate)). It’s probably a little bit more complex an algorithm to track, so I understand why it’s not part of the patterns it can detect. Also, it would be nice if it could flag any folders that were rendered empty after a purge, but I understand that, too, is probably above and beyond.

  False advertising: Can't de-deduplicate cloud storage

  This review is only for de-duplicating files in the cloud, which is what I needed, and what Gemini 2 can't do, despite what it advertises. I didn't try de-duplicating files on my computer. I downloaded Gemini 2 because it says, ""delete duplicates in cloud storage like Google Drive and Dropbox." It can't do that. I tried, eventually wrote to support, and they replied, "there is no possibility to scan your cloud storage with Gemini 2." They suggest downloading all cloud files and then scanning them locally. First, if I had room on my computer for all my cloud files, I wouldn't have much need of a de-duplicator. Second, even if I did download everything, all Gemini 2 could do is delete the additional duplicates that I'd just created in doing so. I'd still have to manually find and delete each corresponding file in the cloud. It's not just the app store that makes the false claim -- their website also says, "Duplicates are sneaky, they don’t just live on your Windows’s hard drive. Our duplicate finder scans and locates hidden copies wherever they are... Cloud Storages (Dropbox, iCloud)..." These false statements resulted in a big waste of my time.

  Great… but some crashes for large data scans

  I was an owner/fan of Gemini vers 1.0 and have recently purchased this version as well. Despite the feedback below, I think its probably the best application for what it does. Here’s what I think works really well, and what I think not so much: The Well: - The duplicate detection is spot on. I’m always paranoid about it not actually selecting duplicate files. More often than not I trust but verify. I’ve never had it screw up the duplicate finding. - The scanning works quickly. - I’m enjoying the smart behavioral selection feature. The Not so Well: - It may be because I have a LOT of files to sort through, but the app crashes a lot with big scans (>50GB duplicates?). - Its very slow sorting through those big scans. - Its tedious to review findings. When sorting I can’t select multiple files within a file set. i.e. if it finds multiple versions of a particular file, and want to manually select or unselect for removal. It has to happen one at a time, and there’s a delay for each one. - I love I can export detected duplicates to a text file, but I can’t actually bring those back into the application to re-process. If there’s a crash it doesn’t always remember my previous selections, and this file export requires me to use another tool to process and remove.

  Unable to delete photos in Photos and only works on default System Photo library

  After finding a lot of duplicates, it was unable to delete the photos from within Photos, and instead created a separate album called Gemini Duplicates. Now what is the point of going through over 1000 photos in Gemini Duplications album ONE BY ONE to do right click > Show in All Photos > and then Delete?? If you just hit delete it only removes it from that album and not the actual library! I'm definitely not going to go through 1000 photos to delete them one at a time obviously. Also, why does this not work with whichever library you have open currently in Photos? A lot of people have multiple libraries so it should not require it to be the default system library. Thanks for the trial but I would not be paying for this until these issues are addressed

  Exactly what I needed!

  I started using Gemini 2 because I have a huge mess of photos and videos that have accumulated over the years that I'm sorting. Other apps were such a pain that I had decided just to do it manually until I looked into Gemini 2. The feature that I love the most is that you can perform a scan once, begin to delete files, take a break or close the app entirely, and then reopen it and basically just pick up where you left off. I have thousands of files in the scans that I've done and haven't had the app crash or experience any issues. My biggest critique is that I wish there was a way to quickly tell Gemini 2 to disregard. The app has the ability to disregard files and folders which is great. But it's a pain to have to enter them in manually. When going through the files after the scan, it would be nice to have a box to check to disregard the files or perhaps grey them out -- I have files that I need to be in multiple places or some of the similar files identified are definitely similar, but are still distinct and I need to have them.
