This program is extremely useful. I have recently performed a recovery on a bricked Microsoft Surface and was able to extract all the useful files from a Windows home directory and quickly discard all the libraries, caches, and so on. By seeing the folders that take up the most space you can easily determine what the juicy bits in a folder hierarchy are. Huge time saver. Using GrandPerspective on macOS was a similar revelation, but ncdu being keyboard driven and allowing you to quickly launch a shell inside each folder and then apply find -exec there quickly is a productivity boost on yet another level.
