Test interactively first
Build and test cleaner selections in the graphical interface before automating them.
Keep automation narrow
Scheduled cleanup should focus on known temporary data rather than every available cleaner.
Verify runs
Check free space and normal application behavior after automated maintenance, especially after software updates.
Frequently asked questions
Should I use Preview first?
Yes. Preview helps review the scope before data is removed.
Should every cleaner be enabled?
No. Select cleaners for a specific goal and only when you understand the data involved.
What after changing settings?
Run a small cleanup and verify normal Windows and application behavior before expanding the scope.
