OneDrive typically does not duplicate files on its own; however, there could be several reasons why you might be experiencing duplicated files. Here are some common causes and potential solutions:

  • Syncing Issues: Check if there are any syncing issues with OneDrive. Sometimes, syncing problems can result in files being duplicated. Ensure that your files are fully synced before making any changes.
  • Conflicting Files: If you have multiple devices connected to the same OneDrive account, conflicting changes may occur. For example, if you edit a file on two different devices simultaneously, it might create OneDrive duplicate files to preserve both versions.
  • File Explorer Integration: If you're using the OneDrive integration with File Explorer on Windows, be cautious with how you move, copy, or save files. Sometimes, issues in the integration can lead to duplication.

In the following parts, we will show you how to remove duplicate files on OneDrive and how to fix the OneDrive duplicating files issue.
