That's all the files and subdirectories, and multiple levels of subdirectories, shown _at the same time_. Without needing to navigate in and out of directories. If there's a way to do this using ncdu, then I've failed to find it. Screenshot please.

    BTW, here's my ncdu screenshot: --- /mnt/src/6/linux-4.9-rc5 --------------------- 401.7 MiB [##########] /drivers 135.6 MiB [### ] /arch 37.3 MiB [ ] /fs 35.3 MiB [ ] /include 34.4 MiB [ ] /Documentation 32.2 MiB [ ] /sound 27.6 MiB [ ] /net 13.4 MiB [ ] /tools 7.5 MiB [ ] /kernel 5.9 MiB [ ] /firmware 3.6 MiB [ ] /lib 3.4 MiB [ ] /scripts 3.3 MiB [ ] /mm 3.2 MiB [ ] /crypto 2.3 MiB [ ] /security 1.1 MiB [ ] /block 880.0 KiB [ ] /samples 424.0 KiB [ ] /virt [...] I don't see subdirectories.

    While you're going bananas on the pros of flame graphs, a significant con is that most of the names are unreadable. In your example, the legible information is not much more than what 'du -skh linux-4.9-rc5/*' would give you.

      You can click to zoom, but in the default output I wouldn't call it a significant con anyway. It's usually (not always) an advantage. Take that ncdu output above: "/drivers" is visible in the flame graph, whereas "/virt" is not. It's only printing the names of the largest rectangles -- the ones you care about, helping draw your attention to where it should be drawn.
