Fix OneDrive and File Explorer Running Slow on Windows 11
Question details
The user is experiencing severe lag and slow performance in Windows 11 File Explorer when navigating or managing files synced with OneDrive, despite having a fast and stable internet connection.
- Product
- OneDrive
- Device & OS
- Windows 11
- Scenario
- Navigating folders, managing files, or performing routine tasks locally via Windows 11 File Explorer.
- Observed behavior
- File Explorer becomes extremely slow, unresponsive, or lags heavily during interactions while OneDrive is running or syncing in the background.
Before proceeding, ensure that your Windows 11 is fully updated to the latest version and verify via Task Manager that no large file syncing operations are actively consuming all your CPU or disk resources.
Reset the OneDrive Sync App
Resetting OneDrive clears its local cache and restarts the sync engine, which is often the most effective way to resolve File Explorer lag caused by background synchronization errors.
A corrupted cache can cause OneDrive to constantly scan files, heavily loading Windows File Explorer. Resetting the application forces a clean start without deleting any of your locally saved or cloud files.
Press the Windows Key + R on your keyboard simultaneously to open the Run command window.
Copy and paste the following command into the Run window: %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter.
Wait for the OneDrive cloud icon in your system tray (bottom-right corner) to disappear and then reappear. This process may take a couple of minutes.
If the OneDrive icon does not reappear after a few minutes, click the Start menu, search for 'OneDrive', and click the app to launch it manually. Open File Explorer to check if the speed has improved.
Report the Performance Issue to Microsoft
If resetting does not fix the slow performance, submitting a direct diagnostic report to Microsoft can help them identify and patch Windows 11 specific compatibility bugs.

Frequently Asked Questions
Why is OneDrive suddenly making Windows 11 File Explorer slow?
This usually happens due to a corrupted OneDrive cache, the background syncing of exceptionally large files, or compatibility bugs introduced in recent Windows 11 updates that cause File Explorer to constantly index cloud-based files.
Can I unlink OneDrive to stop File Explorer from lagging?
Yes. Unlinking your PC from OneDrive stops the syncing process entirely, which often immediately resolves File Explorer lag. You can do this by clicking the OneDrive icon, opening Settings, navigating to the Account tab, and clicking 'Unlink this PC'.
Will reinstalling OneDrive fix the performance issue?
If resetting the app using the command prompt doesn't work, completely uninstalling OneDrive and downloading the latest version from the official Microsoft website can clear deep-seated configuration errors that cause system slowdowns.
Does Files On-Demand cause File Explorer to load slowly?
It can. The 'Files On-Demand' feature displays files that are stored in the cloud but not physically on your PC. When you open folders containing thousands of cloud-only files, File Explorer may lag while it retrieves the thumbnail and metadata from the servers.
