Question details

Users are experiencing issues where OneDrive resynchronizes files, unexpectedly deletes local folder copies, or creates duplicate files, often after a Windows update or when managing multiple accounts.

How to Fix OneDrive Deleting Local Folders and Creating Duplicate Files

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Synchronizing local computer files with cloud storage, especially when utilizing multiple accounts or recovering from a recent system update.
Observed behavior: OneDrive deletes local file copies during active synchronization, propagates deletions to the cloud, and generates duplicate folders or files when redundant files are copied into a syncing directory.

Before you start

Before proceeding, temporarily pause your OneDrive synchronization from the taskbar to prevent any accidental cloud deletions while you organize your local files and accounts.

Solution 1Recommended

Prevent Deletions and Duplicates During Active Sync

Manage your files correctly while the OneDrive client is actively syncing to avoid accidental cloud deletions and file duplication.

When OneDrive is actively syncing, any action you perform on a local synced folder is immediately mirrored in the cloud. Deleting a file locally will send a command to delete the cloud version as well.

Additionally, manually copying files into a local folder that OneDrive is already trying to download or sync from the cloud will cause a conflict, resulting in duplicate files or folders.

Pause OneDrive sync

Click the OneDrive cloud icon in your Windows taskbar notification area, click the 'Help & Settings' gear icon, and select 'Pause syncing' to safely manage your local files.

Avoid deleting files during sync

If you need to free up local disk space, do not press the Delete key. Instead, right-click the file or folder and select 'Free up space'. This removes the local copy but keeps the file safe in the cloud.

Prevent manual copy conflicts

Wait for a folder to finish showing a solid green checkmark (indicating it is fully synced) before manually moving or copying additional files into that directory.

Prevent Deletions and Duplicates During Active Sync

Restoring Deleted Files: If local files were already deleted and synced, log into the OneDrive website and check the online Recycle Bin to restore them.

Frequently Asked Questions

Why does OneDrive append my computer name to duplicate files?

When OneDrive detects a synchronization conflict—usually because a file was updated locally and in the cloud simultaneously, or copied into a syncing folder—it saves both versions. It adds your PC name to one of the files so you don't lose any data.

Can I link two personal OneDrive accounts on the same Windows desktop?

No, a single Windows user profile officially supports only one personal OneDrive account. To access another personal account, you must either use the OneDrive web interface or create a separate Windows user account on your PC.

How do I safely remove local files without deleting them from OneDrive?

Do not use the Delete key. Instead, right-click the file or folder inside your local OneDrive directory and select 'Free up space'. This removes the local data to save hard drive space while keeping the cloud version fully intact.

Why did OneDrive start resynchronizing all my files after a Windows update?

Major Windows updates can sometimes reset OneDrive's local configuration or change folder path permissions. When this happens, OneDrive performs a full cross-check (resynchronization) to ensure local files perfectly match the cloud, which may temporarily create duplicates if it detects discrepancies.
