Short answer: Treat denied access as a coverage limitation and resolve it through authorized access changes.

When this guide is useful
If access cannot be granted, state that the report is partial. A transparent limitation is more useful than a complete-looking total that silently excludes protected directories.
Recommended workflow
- Record the affected path.
- Confirm the account's intended permissions.
- Ask the owner or administrator for access if needed.
- Repeat the approved scope afterward.
Limits and precautions
Do not take ownership of another user's or system folder merely to complete a report.
Keep a useful record
Record the drive or folder, scan time, application version and the measurement you used. Keep observations separate from proposed changes. If a result leads to a cleanup, record the file owner, backup status and actual free-space change. This makes the result easier to review and helps explain differences in a later scan.
Quick review checklist
| Question | What to record |
|---|---|
| What did you inspect? | The exact volume or folder, not just the PC name. |
| What action is justified? | Repeat the approved scope afterward. |
| What could go wrong? | Do not take ownership of another user's or system folder merely to complete a report. |
Next steps
If the result is unclear, preserve the current report and narrow the investigation to one folder or application. Make one approved change at a time, then repeat the relevant measurement. Avoid presenting a predicted saving as a measured outcome.
