When this guide is useful

Save files and mods may be stored outside the library folder. Check those separately before uninstalling so an otherwise replaceable game installation does not lead to loss of personal progress.

Recommended workflow

Find the library directories.
Compare their totals.
Identify unused installations.
Use each launcher's management controls.

Limits and precautions

Deleting selected game assets directly can trigger repair downloads or break an installation.

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?	Use each launcher's management controls.
What could go wrong?	Deleting selected game assets directly can trigger repair downloads or break an installation.

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.
