Sometimes it’s a challenge to find which folder is taking up all the disk space on your machine. Here are a collection of tools I keep coming back to (although I can never remember the name of ncdu – which is why I’m writing it down in a easy to access place).

Windows:

windirstat
https://portableapps.com/apps/utilities/windirstat_portable

Mac OS X

Grand Perspective
https://grandperspectiv.sourceforge.net

Linux (in shell)
Ncdu
https://dev.yorhel.nl/ncdu

All do a similar thing, just with different outputs.
