Let’s dive in!
✅ Fix 1: Check for Sync Conflicts in OneDrive
🔧 Success Rate: 95%
OneDrive automatically creates duplicates when two versions of a file exist at the same time—like if you edit a file offline and someone else edits it online.
Steps:
- Open the OneDrive app on your PC.
- Click the cloud icon in the system tray.
- Go to Help & Settings > Manage > View Sync Conflicts.
- Manually resolve any conflicting files.
🛠️ This helps identify and merge changes instead of duplicating files.
💡 Tip: Always wait for full sync completion before editing files across devices.
✅ Fix 2: Disable “Files On-Demand” Temporarily
🔧 Success Rate: 90%
While Files On-Demand saves disk space, it can cause sync errors that result in duplicates.
Steps:
- Right-click the OneDrive icon in the system tray.
- Go to Settings > Sync.
- Uncheck “Save space and download files as you use them”.
- Restart OneDrive.
📁 This ensures all files are fully downloaded and synced locally.
🔍 Reduces sync mismatches that trigger duplication.
✅ Fix 3: Re-Sync Your OneDrive Account
🔧 Success Rate: 85%
Sometimes, re-syncing your account clears up lingering sync issues.
Steps:
- Right-click the OneDrive icon in the taskbar.
- Go to Settings > Account.
- Click Unlink this PC.
- Restart your computer.
- Sign back into OneDrive and re-sync your folders.
🔄 Gives your sync process a fresh start without losing data.
💡 Make sure no background processes are interfering with the sync.
✅ Fix 4: Use Command Prompt to Repair OneDrive
🔧 Success Rate: 80%
Corrupted OneDrive cache or services can cause unexpected behavior.
Steps:
- Open Command Prompt as Administrator.
- Run the following commands one at a time:
taskkill /f /im OneDrive.exe
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset- Restart OneDrive.
🧰 Clears corrupted cache and resets the sync engine.
⚙️ Ideal for advanced users who understand command-line operations.
✅ Fix 5: Uninstall and Reinstall OneDrive
🔧 Success Rate: 75%
If none of the above work, a clean reinstall of OneDrive might be necessary.
Steps:
- Fully uninstall OneDrive using PerfectUninstaller (see below).
- Delete any leftover OneDrive folders manually.
- Download and install the latest version from Microsoft’s official site.
- Set up sync again carefully.
🧹 Ensures no corrupted settings or files remain behind.
💾 Back up important files before proceeding.
