I back up all my files on Dropbox. Over the years, I am sure that I have many duplicate files and I would like to detect and remove them. I know that there are many software solutions to detect and remove duplicates, but the challenge is that I use the online sync-only feature of Dropbox, so most of my Dropbox files are only available online, not on my local computer. For example, I have around 1.5 TB of files in my online Dropbox but my local computer can store less than 500 GB. If I were to compare files with the typical duplicate finder, they would download all my Dropbox files locally to do the comparison. Even if I were willing to do that (which I am not), my local disk does not have the capacity to do that.

How can I detect duplicates among my Dropbox files? In my case, I do not need to compare file contents. I can assume that files are duplicate if the filename and size is identical (not the date). How can I detect such duplicates entirely in my Dropbox online files without downloading anything locally?

Based on searching, the only third-party solution I have found that seems to offer this functionality is Sorcim's Cloud Duplicate Finder. I am hesitant to give access to my Dropbox to an unknown company and its solution is rather expensive (minimum 40 USD for three-month access). However, if there is no more affordable solution and someone can help me verify its trustworthiness, I would definitely consider an option like this.

  • @BlindSpots I see the text you mentioned, but I cannot find any "Find Duplicates" option in my Dropbox and there are no details on the page you linked. Do you have more details about this?

If you haven't solved this already, you might want to take a look at the Detect duplicates on Dropbox workflow from SimWorkflow.

It uses the Dropbox API to retrieve file metadata and compares hashes for all files to generate a summary of duplicate files. It does not access the file contents directly.

Disclosure: I am the founder of SimWorkflow, but I am also using it to help me find duplicates on Dropbox. :)

  • It would be helpful to explain if it addresses the second part removal.

  • Another HTTP Task can be added in to remove the duplicates, it's intentionally not to have the removal part. However, it addresses the key question: "How can I detect such duplicates entirely in my Dropbox online files without downloading anything locally?"
