How to Fix File Explorer Freezing While OneDrive Syncs
Question details
The user is experiencing an issue where File Explorer becomes completely unresponsive during OneDrive file synchronization operations.

- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Creating, renaming, copying, moving, or editing files in a folder that OneDrive is actively synchronizing to the cloud.
- Observed behavior
- File Explorer freezes and becomes unresponsive during file sync operations. The issue may persist even after reinstalling OneDrive or altering Windows profiles.
Before attempting the fixes below, try temporarily pausing OneDrive syncing from the taskbar icon to confirm if the background sync process is the direct cause of File Explorer freezing. Also, ensure your Windows OS is fully updated with the latest patches.
Reset the OneDrive Client
Resetting the OneDrive application clears its cache and resolves underlying sync conflicts that can cause File Explorer to freeze.
A heavy backlog of pending syncs or a corrupted cache file within the OneDrive client is a common cause for File Explorer lockups. Resetting the client forces OneDrive to re-check all files and rebuild its sync database without deleting any of your personal data.
Press the 'Windows Key + R' on your keyboard simultaneously to open the Run dialog box.
Type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' into the text box and press Enter or click 'OK'.
Observe the OneDrive cloud icon in your system tray (bottom-right corner). It will disappear and should reappear after a minute or two. If it does not reappear, open the Start menu, search for 'OneDrive', and click it to launch the application manually.

Test Synchronization in a New Local Windows Profile
If resetting OneDrive doesn't work, your current Windows user profile might be corrupted. Creating a new profile helps isolate the problem.
Collect Logs and Contact Microsoft 365 Support
If the issue persists across different profiles, advanced logging and investigation by Microsoft support are necessary.

Frequently Asked Questions
Why does OneDrive cause File Explorer to freeze?
This typically occurs when there is a conflict in the Windows user profile, a corrupted OneDrive cache, or when a massive batch of files is actively syncing, which overwhelms File Explorer's processes.
Will resetting my OneDrive delete any of my synced files?
No. Running the reset command only clears the OneDrive application settings and sync cache. All your files stored locally in the OneDrive folder and online in the cloud remain untouched.
How can I quickly pause OneDrive to stop File Explorer from freezing?
Click the OneDrive cloud icon in your taskbar, click the gear icon (Help & Settings), select 'Pause syncing', and choose a duration (such as 2 hours). This stops the background processes and often restores File Explorer responsiveness immediately.
Can a Windows update fix OneDrive syncing problems?
Yes. Microsoft frequently releases patches that address bugs between File Explorer and OneDrive integration. Check for updates by going to Windows Settings > Update & Security > Windows Update.
