Fix ‘The Action Cannot Be Completed’ File-in-Use Error in Windows
Source-checked About 10 minutes
Answer
Save your work, close the app using the file, and try again. If the owner is unclear, restart Windows or use Microsoft's PowerToys File Locksmith to identify the locking process.
Confirm the symptom and protect the current Windows state
Record the Windows build, affected app or device, exact message, and the last change before the symptom began. Save open work, keep installers and recovery credentials, and create a current backup or restore point when the supported recovery may change apps, drivers, partitions, or system files. Test one supported change at a time so a useful result can be attributed and reversed.
Start with the supported check
Close every app that may have the file open, including preview, sync, archive, and media apps.
Apply the current setting
Try the action again. If it remains blocked, restart Windows to release ordinary file handles.
Test the result
For a persistent lock, install Microsoft PowerToys, enable File Locksmith, right-click the file, and choose Unlock with File Locksmith before ending only the identified process.
Verify the intended result before broader recovery
Repeat the exact task described by “Fix ‘The Action Cannot Be Completed’ File-in-Use Error in Windows” with a harmless test. Confirm the affected app, account, device, file or setting now matches the Answer, then recheck it after one fresh session or restart when that is part of the supported workflow. Keep the original data and recorded starting state until the result is stable; if only one component still fails, keep further recovery limited to that component.

If it does not work
- If Windows still reports the file as open, record its full path and identify the owning app through Task Manager or Resource Monitor. Close only that process or restart Windows; do not force-delete a system, synced, encrypted, or actively saving file.
