DeDuplicate finds and removes duplicate files in your cloud storage.

Google Drive, OneDrive, Dropbox etc. don't have built-in tools to detect and delete duplicate files like photos, videos, documents...

This app scans your files, searching for duplicates and allowing you to delete all the extra copies! Saving space and tidying up.

How does it work

  1. Download and install DeDuplicate on your device.
  2. Pick a cloud service and log in to your existing account.
  3. Choose which folder(s) to scan, or the entire drive, and wait a short while!

  4. Review the list of all the duplicates that have been found.
  5. Optional: choose which copies to ignore.
  6. Confirm the operation.

That's the gist of it! Read more in the guide.

Other than its ease of use, the main highlights of DeDuplicate and its unique selling points are...

  • It's completely free, without limitations or paywalls: there are no restrictions on the number of files you can scan or delete.
  • It’s not resource-hungry: it doesn't need to download the files in order to identify duplicates. Instead, it requests metadata about them from the cloud providers. So it doesn't waste bandwidth or need a lot of free space on your device, and...
  • It's very fast, and the time varies with the NUMBER of files, not their size.
  • It identifies exact duplicate files precisely. If two or more files happen to have the same size or similar names, they are not counted as duplicates. They MUST have the same content!
  • The entire process takes place on your device. There's absolutely no data collection about your files: no information gets through intermediary servers or anything because the app communicates directly with the cloud provider.
  • You don't need to create an account, you just have to log in to your cloud service and give the app the required permissions.
  • No subscriptions or hidden costs. If you want to support the development of the app you can do it on a voluntary basis, there are some options. More on that later.

Use Cases

  • By mistake or because of some synchronization problem, you uploaded a bunch of files twice or more, and you want to get rid of them avoiding the nightmare of doing it manually.
  • In your phone, you enabled the auto-backup feature for the media folders of a messaging app that you use daily (for example, WhatsApp). Sometimes those images and videos are received and forwarded more than once, accumulating unnecessary copies that get backed up in the cloud anyway.
  • You have OCD tendencies and you feel the urge to clean things up :)

This app comes with ads, but they don't get in your way too much: they appear one time before the scanning and deletion process. And if you want to remove them altogether, there's an in-app purchase option... but you don't need to do it. The app is always full-featured, not a watered-down version.

If you wish to donate, there's an in-app purchase specifically for giving me a tip!
