Reasons to Delete Duplicate Files in OneDrive?

Duplicate files don’t just occupy storage space; they can also complicate your data management. Removing duplicate items in OneDrive will:

  • Clear potentially valuable cloud storage space.
  • Optimize file organization and syncing time.
  • Prevent confusion when opening shared files.
  • Maximize storage and enhance performance.

Two Ways to Delete OneDrive Duplicate Files

There are essentially two methods of removing duplicate files:

  • Manual Methods: Best for a small amount of data.
  • Automated Tool: Best for bulk eradication of duplicate files, and the accuracy is 100%.

Let’s go through both options.

Manual Methods to Remove Duplicate Files From OneDrive

These approaches are suitable for users who do not use a large number of files and who opt for a manual approach.

#1 Method to Remove Duplicate Files in Microsoft OneDrive

OneDrive’s built-in search function can be used to find and compare duplicates. Simply follow the next steps:

  1. First, start by opening OneDrive on your computer or browser.
  2. Then, use the search box to find the files with the same name or file extension.
  3. After that, sort the results by Name, Date Modified, or Size to quickly compare and filter data.
  4. At last, manually look for duplicates and delete those files.

#2 Method to Delete Duplicate Files in OneDrive

Windows File Explorer is another way to find duplicates if OneDrive is synced locally.

  1. Initially, open the local OneDrive folder on your computer.
  2. Now, in the search box, type in any file extension and hit enter to show you all files in the folder.
  3. Then, sort files by Name or Size to make it easier to compare the files.
  4. At last, manually look for duplicates and delete the extra copies.

Limitations

  • Difficult and lengthy methods for big data.
  • high chance of unintentionally erasing crucial files.
  • No automatic detection of duplicates.
  • Duplicates across several folders or accounts are hard to find.
