Record the starting point
Before making changes, check available space and note the folders you plan to review.

When a computer holds too much clutter, people usually want a clear route toward a tidier state rather than a complex diagnosis.

This makes it easier to understand what helped and what can be safely reversed.
File cleanup will not fix overheating, disk failure, malware, or a hardware problem.
