How to Remove Unwanted Files Synced to OneDrive from Another PC
Question details
The user needs to remove unnecessary files that were unintentionally uploaded to OneDrive after connecting an old computer, disrupting their existing folder organization.

- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Connecting an old computer to an existing OneDrive account with automatic folder backup enabled.
- Observed behavior
- Unwanted files from the old computer are automatically uploaded to the cloud, cluttering business storage and folders without a clear identifier of which PC uploaded them.
Before deleting any synced files or changing your backup settings, temporarily move important local files to a folder outside of OneDrive's sync path to ensure they are not accidentally lost.
Manually Delete Files and Stop Unwanted Folder Backup
Use OneDrive settings to stop backing up folders from the old PC to prevent future unwanted syncs, then manually clean up the cloud storage.
OneDrive's PC Folder Backup automatically syncs your Desktop, Documents, and Pictures folders to the cloud. When an old computer is connected, its outdated files merge with your current cloud storage. To fix this, you must disable the backup feature on the old computer and manually delete the clutter.
On the old computer, locate any files from the Desktop, Documents, or Pictures folders that you want to keep locally and move them to a temporary folder outside of OneDrive (e.g., directly to the C: drive).
Click the OneDrive cloud icon in your system tray on the taskbar, click the gear icon for Help & Settings, and select 'Settings'.
Navigate to the 'Sync and backup' or 'Backup' tab in the settings window, then click on the 'Manage backup' button.
Toggle off the switch or click 'Stop backup' for the affected folders (Desktop, Documents, or Pictures) to prevent the old PC from uploading files to the cloud.
Open your OneDrive folder in File Explorer or log in to OneDrive online, identify the unwanted files that were previously synced from the old PC, and manually delete them.

Frequently Asked Questions
Why does OneDrive sync files from my old computer automatically?
By default, OneDrive may have 'PC Folder Backup' enabled for the Desktop, Documents, and Pictures folders. When you sign in to your OneDrive account on an old computer, it detects these files and automatically uploads them to the cloud to keep them synced across all devices.
Will stopping OneDrive backup delete files from my computer?
When you stop a folder backup, the files currently stored in your OneDrive stay in the cloud, while any new files you create will stay only on your local computer. However, your local Desktop or Documents folder may temporarily appear empty because the old files remain in the OneDrive folder; you can manually move them back to your local PC.
Can I find out which computer uploaded a specific file to OneDrive?
Unfortunately, OneDrive does not natively display the specific computer or device name that uploaded a file in its standard version history or details pane, which is why manual file identification and cleanup is required.
