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 very fast, and the time varies with the NUMBER of files, not their size.
  • It’s not resource-hungry: it doesn't need to download the files 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.
  • 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: your license (where applicable) is linked to your platform's app store account.
  • No ads! And no personal data collection.

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 :)

Pricing and conditions may vary from time to time, depending on the platform and other factors! I'm testing different pricing models before settling for one in particular.

This is the current situation:

  • The version for iOS and MacOS is paid upfront, with no subscriptions. It's offered as a "universal purchase": buy once, run it on all your Apple devices (iPhone, iPad, and Mac).
  • The Windows version is also a one-time payment and offers a trial period of 24 hours.
  • The Android version is subscription-based after a trial period of 24 hours.

The app is always full-featured and no version is watered-down, not even the trials.

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