Where does my disk space go?

I have nearly 400 gigabytes storage in my desktop. Some people will tell that this is a lot, some that it is quite small size. But everybody agrees with one simple rule: “there is no such thing as big enough storage”.

From time to time I have situation when I lack space for my projects (which can take 17GB in one run). In such moments there is one solution handy: removing not needed data. But how to check what takes most of space?

Some time ago I discovered ncdu application. It offers simple interface with all required informations — list of directories with space used (all sorted by size). User can walk through directory structure, remove not needed ones, recalculate directory use — everything what is needed in such tool.

Few minutes later 40GB from old builds recovered ;)
