✅ Step 1: Run CHKDSK to Repair File System & Remove Invalid Reparse Points

This is the primary fix recommended by Microsoft.

1. Open Command Prompt as Administrator.
2. Run: chkdsk r /f
3. If the volume is in use, you’ll be asked: “Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)”.
   Type Y and press Enter.
4. Reboot your PC. CHKDSK will run before Windows loads, scanning and repairing file system issues and removing invalid reparse points.
5. After reboot, try the file / folder operation again.

Because OneDrive uses reparse points for Files On-Demand, CHKDSK cleans up those that are invalid or broken.
