[Easily & Effectively] Remove Duplicate Files in Microsoft OneDrive
"I have faced an issue regarding OneDrive, all the files and folders inside OneDrive are being duplicated. Is there any way to remove it?"--from Microsoft Community
OneDrive makes work more convenient for its allowing to sync files among multiple devices. However, if multiple users are sharing the same folder on their own OneDrive and a computer is disconnected and then re-linked before syncing and uploading the data, it may result in conflicting data that can lead to duplicate files. Quite a few users have reported duplicate files in cloud space. These extra replicas not only mess up the file library, but also eat up cloud storage, which is usually 5GB if you haven't purchased more space. However, there's no need to worry about the file duplication issue. The solution for efficient and safe removal of duplicate files is right here in this article.

Part 1: Why would OneDrive duplicate files?
Duplicate files in OneDrive may appear for the following two reasons:
Synchronization of the same file on multiple devices. When OneDrive detects a file sync conflict, it creates duplicate file names and saves all copies. For example, if a file is edited on more than one computer before it is synced across devices, Onedrive will save different versions of the file in order to prevent data loss.
Duplicate uploads of the same file. Users can mistakenly upload or send the same content to OneDrive more than once. In common case, OneDrive will prompt you that the file already exists. But, if you upload the same file to different folders in cloud space, it may not be detected.
Duplicate files created in OneDrive usually are named two ways: With computer names added to the filename or with "Copy" or numbers in parentheses next to filename. Duplicate files combined with a computer name in the filename are usually caused by one OneDrive account being used on multiple devices or the same shared folder being added to multiple OneDrive accounts. By adding the computer name as a suffix, OneDrive is able to distinguish between files that were changed from different devices.
Part 2: How to remove duplicate files from OneDrive?
Manual deletion seems to be the most straightforward method. Duplicate files have identical file type and size with similar file names. You can access the OneDrive folder through File Explorer and search for duplicate files by other computers' names.
