It would be much better that it can support directly scanning a Cloud drive. ### 5/5 — Awesome cleanup tool *2026-01-06, version 6.5.0* Saved me so much space! Really liked how it grouped everything clearly before deleting. ### 5/5 — Good *2025-12-14, version 6.5.0* I've tested this Duplicate Finder and I found that it is very good at finding the duplicate files but the process to select what to delete is a bit cumbersome. It would be great to be able to see the full File Path of each highlighted file in the Results windows, instead of having to press the Delete in Finder button for each file. I could not find a setting for this - is it possible? ### 5/5 — Super impressed *2025-12-12, version 6.5.0* My Photos library was a mess, but this app organized everything perfectly. The similar image detection is amazing. ### 5/5 — The app is helpful! *2025-11-05, version 6.5.0* The app is helpful if your storage space is not enough, it runs fast to scan all the duplicates from my Mac and delete them in bulk. ### 5/5 — Reliable and safe to use *2025-10-18, version 6.5.0* Tried a few others before, but Cisdem is by far the most duplicates it found out. What's more, it shows everything clearly before deleting, so I can review and confirm. Feels safe to use. ### 5/5 — The best! *2025-10-17, version 6.5.0* The interface is clean and simple, Not just for photos, it finds duplicate documents and archives deeply hidden in folders. Totally worth it. ### 5/5 — Cleared up my seagate drive instantly! *2025-10-16, version 6.5.0* I used Cisdem Duplicate Finder to scan my external Seagate Expansion HDD, it freed up so much space and I was shocked at how many duplicate videos were eating my storage. ### 5/5 — Finds duplicates quickly *2025-09-09, version 6.5.0* I’ve been struggling with duplicate files taking up space on my Mac, and Cisdem Duplicate Finder solved it perfectly. The scanning is fast, it finds all duplicates including hidden ones, and the preview feature makes it easy to decide what to delete. After cleaning up, I’ve freed up a lot of storage. Highly recommend for anyone looking to declutter their Mac! ### 5/5 — Alles funktioniert reibungslos! *2025-09-07, version 6.5.0* Das Scannen des Fotoverzeichnisses auf dem Qnap NAS funktioniert einwandfrei, die Duplikate werden nach Abschluss des Scans aufgelistet, und alle markierten Duplikate wurden entfernt, nachdem ich auf Löschen geklickt habe. Ich habe die Dateien gerade im Finder überprüft und es sind keine Duplikate mehr vorhanden. ### 4/5 — Failed to detect black and white images *2025-09-06, version 6.5.0* I'm using Cisdem Duplicate Finder for about a year, and I like it very much. I believe it's probably a small bug that it cannot correctly detect black and white images. For the other colorful images, it detects perfectly without any errors. ### 5/5 — Saved me from buying extra storage *2025-08-07* I was about to upgrade my iCloud plan because of space issues. Instead, I used Cisdem Duplicate Finder and recovered over 25GB of duplicate files. The interface is super clear and lets you review everything before deleting. Highly recommend! ### 5/5 — The best tool I've tried! *2025-08-07, version 6.5.0* I tested a few duplicate finders, and this one gave me the most accurate results. It scans all types of files and always brings you an accurate result. The ability to auto select duplicate files for deletion also works greaty. ## Most critical reviews (10 lowest-rated) ### 1/5 — Trash App *2026-06-05, version 6.5.0* Missing the most important task, being able to select all the not found songs in the music app and deleting them. Waste of $$$ ### 1/5 — Duplicates *2026-04-04, version 6.5.0* Will not delete duplicates ### 1/5 — Hard to see what’s what *2025-12-20, version 6.5.0* It’s good that theoretically you can see files ‘side by side’ but the program defaults to deleting all duplicates, so you can’t easily test to see where you are deleting from. I tried to delete all my files from OneDrive that I’d copied to my iCloud, but it seemed to be deleting them from iCloud which was a disaster. ### 1/5 — Old software? Support is slow *2025-11-04, version 6.5.0* My guess is that this is really old software that the company is milking for revenue. I have been reaching out to their support team with very slow and unhelpful responses so far. Over several weeks, I have attempted to use this software multiple times. It is terribly slow to the point it is not a practical tool. I calculated that if I let it keep running, it would take 39 days to complete the job. I am wondering what will come first. The software completing the job, or getting a response from their support team that actually addresses the performance issue. ### 1/5 — does not work *2025-08-06, version 6.5.0* found 4 dup photos out of 100s dups I have and then asked to upgrade to paid version to do anything! Scam! ### 1/5 — A PAGAMENTO MASCHERATO *2025-02-20, version 6.5.0* Scaricata, cerca i duplicati, te li fa selezionare e poi... quando vuoi cestinarli devi pagare! Ma andate al diavolo. ### 1/5 — No Customer Support post purchase *2025-01-10, version 6.5.0* I liked the app and bought licence through their website. For that to work, you also have to download the app from their website as the App Store version is somehow different. Now I am wanting to tranfer to my new Mac but they need to send me a new licence as it’s not automatic. I haven’t received any reply through their suggested mail, been waiting for long and my work is halted due to it ### 1/5 — Didn't work on Ventura *2024-12-25, version 6.5.0* It spent a long time processing, and then when I came back to check out how it was doing, it's screen was blank. Tried to save the project but nothing saved. ### 1/5 — A pagamento *2024-08-11, version 6.5.0* Per eliminare i file una volta scansionati bisogna pagare oltre 20€ ### 1/5 — Did not work. *2024-06-05, version 6.5.0* Graphic says the duplicates were deleted but the duplicates are all still in the music file. Waste of money. ## Most praised reviews (10 highest-rated) ### 5/5 — Simple and effective *2026-07-09, version 6.5.0* I liked how straightforward it is—no confusing settings, just scan and delete. It picked up duplicates in my photos and documents really well. ### 5/5 — Reliable duplicate cleaner *2026-07-02, version 6.5.0* Works exactly as expected. The interface is clean, and it handled a large number of files without slowing down my system. ### 5/5 — Quick and accurate *2026-06-25, version 6.5.0* " Scanned my entire Documents folder in minutes and flagged duplicates I didn't even know existed. Deleted them confidently thanks to the preview. Highly recommend." ### 5/5 — A good app *2026-05-14, version 6.5.0* This is a good app, it really works for removing duplicate files and releasing free space. ### 5/5 — Very Accurate *2026-04-10, version 6.5.0* I could scan multiple folders and remove duplicates at once without worrying about losing the original files. ### 5/5 — Great for cleaning up storage *2026-04-10, version 6.5.0* This app helped me recover a lot of storage space by detecting duplicates on my computer and external drives. ### 5/5 — Récupération d’espace facile et efficace *2026-03-15, version 6.5.0* "Cisdem Duplicate Finder est un outil très pratique pour retrouver et supprimer les fichiers en double sur mon ordinateur. L’interface est claire et facile à utiliser, et le scan est rapide et précis. J’ai pu récupérer beaucoup d’espace de stockage sans risque de supprimer des fichiers importants. Je le recommande vivement !" ### 5/5 — Good *2026-03-04, version 6.5.0* Perfect for cleaning photo libraries and old backups. ### 5/5 — Works Well on Large Libraries *2026-03-04, version 6.5.0* Scanned my external drive with no issues. Takes a bit of time on very large scans, but results are accurate. ### 5/5 — Does exactly what it promises *2026-02-27, version 6.5.0* Fast scan, accurate results, and very easy to use. Cleaned up hundreds of duplicate files in minutes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
