How to Remove Log Files on Windows

Before You Clean

Logs and crash dumps can explain a failure. Their size can justify cleanup after diagnosis, but deleting them first can remove evidence you need.

Review and Clean Manually

1. Record the fault and decide whether support needs the logs or dumps. Copy relevant diagnostics into the job record before removing them.

2. Use the OS storage cleanup controls or the affected app’s own log-retention settings where available.

3. Review the exact log or dump category and its age. Keep evidence for unresolved crashes or update failures.

4. Do not clear active system logs or entire system directories as routine maintenance.

5. Compare disk free space afterward. If large reports keep returning, investigate the underlying fault.

Where Kudu Helps

Kudu lists supported log, error-report, and dump targets for review. Keep the categories you need for diagnosis unselected or excluded. File deletion cannot fix the fault that produced the report.

Open Clean up > System Cleaner and run Scan. Review the relevant category and expand its results to inspect the paths. Set exclusions for anything you need to keep, then check the full selected total before Clean. Results search filters the view; it does not erase selections elsewhere.

After cleaning, check the summary and Activity > Cleanup receipts for removed, skipped, or failed items. A receipt is an outcome record, not a backup. Recovery Centre restores supported settings, not deleted files. Compare actual disk free space and test the original symptom; cache removal alone is not a promise of better performance.
