I've been using WizTree anytime I use Windows and want to analyze my disc space and do some organization or cleanup. It is very fast and intuitive and makes cleaning a breeze.
Previously, I'd have to manually traverse directories in file explorer to see file sizes and create a hierarchy in my head.
This software creates the hierarchy in seconds and presents it in a tree format. It's really good.
