When this guide is useful

An old operating system image may no longer be needed for routine installation but could document a specific lab environment. Agree on retention before deleting files shared with other users.

Recommended workflow

Inspect your download and archive folders.
Locate likely image files.
Record their software and version.
Check whether another verified copy exists.

Limits and precautions

A recognizable filename does not prove the image is authentic or replaceable.

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?	Check whether another verified copy exists.
What could go wrong?	A recognizable filename does not prove the image is authentic or replaceable.

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.
