About this app

Please note: DeDuplicate now requires an in-app purchase. Scanning drives remains free, but to remove duplicates you need either a small monthly subscription or a one-time purchase for unlimited use.

———————————————————————————————————

Google Drive, OneDrive, Dropbox, and other cloud services don’t offer built-in tools to find and remove duplicates.

If you store many files in the cloud, it’s easy to lose control and waste space. Automatic mobile backups make this problem even worse.

DeDuplicate scans your cloud storage, finds identical files, and lets you remove the extra copies to free up space.

How it works:

1) Log into your account.
2) Choose one or more folders (or the entire drive) and start the scan. Scan time depends on the NUMBER of files, not their size.
3) Review the detected duplicates and optionally ignore some of them.
4) Confirm the operation.

What makes DeDuplicate different:

• Efficient and fast: files are NOT downloaded. DeDuplicate uses metadata provided by cloud services, so it saves bandwidth, requires no extra storage, and scans are very quick (e.g. ~100,000 files in under 10 minutes, depending on network speed).
• Accurate detection: only EXACT duplicates are detected using file hash values. File names are ignored; contents must be identical.
• Privacy-first: everything runs locally on your device. The app connects directly to cloud providers, with no intermediary servers and no file data collection.
• Cross-platform support.

DeDuplicate currently supports the following cloud services:
(PERSONAL ACCOUNTS - see notes below!)

• OneDrive
• Dropbox
• Google Drive (∗)
• MEGA
• Box
• pCloud
• Yandex.Disk

IMPORTANT: DeDuplicate is designed and tested primarily with PERSONAL/CONSUMER ACCOUNTS. Business, school, or enterprise accounts may behave differently and are not fully supported yet. Improving support for those account types is planned for a future update!

NOTES ABOUT GOOGLE DRIVE:

- Due to recent changes in Google’s requirements for third-party apps, DeDuplicate currently does not have a “verified” status. You can still use Google Drive normally, but signing in requires a small workaround, which is explained step by step inside the app!
- Google proprietary file types (such as Google Docs, Google Sheets, etc.) are treated specially by Google Drive and are NOT included in DeDuplicate’s scan.

WHY DO YOU NEED THIS APP?

Until now, the only practical way to remove duplicates from cloud storage was a very time-consuming workaround: downloading everything to your computer, using one of the many “offline” duplicate-file utilities, and then syncing the changes back to the cloud. In the worst-case scenario, this even means re-uploading everything from scratch. That’s hardly a viable option when you have over 500 GB of unorganized cat pictures :)

DeDuplicate is actively developed. If you encounter any issues, please take the time to contact us!

easy to connect and use. definitely made with users in mind. sorts duplicates into groups, allows you to be able to go to file for preview, works very quickly. it only allows the option to delete all but one or keep all. it doesn't allow to choose one or two. and it only allows us to scan one drive at a time we can't scan two drives at once. it's a great app and so accurate even if name and dates is different.

That's pretty sorry, that you have to pay to remove the duplicates! ESPECIALLY when you put "totally free duplicate cleaner" in the search bar! Like so many of these ripoff apps, this sorry app is no different than the other rip-offs!! VERY MISLEADING! I thought this one was different! Hell, you don't even list Prime photos... soooo I'm uninstalling this garbage, and will be warning everyone I know about this garbage!

Perfect. I've been using a auto sync app for my cloud services and there's nothing to stop it from making duplicates. So each time I have done an upload without deleting it creates another set of duplicates. I have thousands of photographs so it created thousands of Supercuts. This was exactly what I was looking for. It works with most cloud services it is quick and effective. They do not collect unnecessary information. It's so much better than selecting them one by one.
