When this guide is useful

If a large file lives in a game installation, use the game launcher to uninstall or relocate it. Directly deleting an asset can break updates or force a larger download later.

Recommended workflow

Scan the affected volume.
Open the file list.
Sort descending by size.
Check each candidate's complete location.

Limits and precautions

Largest does not mean least useful or safe to delete.

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 each candidate's complete location.
What could go wrong?	Largest does not mean least useful or safe to delete.

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.
