Verify a Cleanup with Before and After Measurements

Short answer: Use actual available space and a repeat scan to verify the result of an approved cleanup.

When this guide is useful

If several jobs run at once, the free-space change cannot be attributed confidently to one cleanup. Keep changes small and document competing activity when an exact comparison matters.

Recommended workflow

Record available space before the action.
Complete one cleanup operation.
Measure available space again.
Repeat the original scan scope.

Limits and precautions

Estimated savings and measured savings should be reported separately.

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 original scan scope.
What could go wrong?	Estimated savings and measured savings should be reported separately.

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.
