Found a >100GB accidental “livestream” recording on one computer. Would have taken forever to find what was taking up all the room otherwise.
GUI apps for this task like GP and the like are more visually complex than they need to be.
One gotcha for me is ncdu2 going Zig and Zig dropping support for OS versions as Apple does.
