Compare the right numbers
Use Preview and cleanup results rather than relying only on rounded Explorer free-space values.
Caches return
Browsers and Windows services can recreate caches quickly after cleanup.
Find larger users
For substantial recovery, inspect downloads, media, virtual machines, installers, and other large user data.
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.
