This scan identifies a variety of items, including previous Windows installation files left over from major updates, system error memory dump files, thumbnails generated by file explorer, and leftover data from recent application uninstalls.

Users are presented with a checklist, accompanied by descriptions for each category explaining what the files are and whether it is safe to remove them. Nothing is deleted automatically without explicit user confirmation. This design ensures that individuals remain in complete control of their data.
