I tried the others, they take it the wrong way.

**ncdu allows to exclude folders like **: monted drives, special drives.

on arch:

ncdu --exclude '/run' --exclude '/media' --exclude '/proc' /

now it really helps, it is fast.

On my laptop I usualy type

sudo ncdu -xr /

-x excludes other disks. I run separate ncdu for every partrition.

Not better than du in my eyes...

sudo du / --human-readable --threshold=+1024MB --one-file-system

Not quite as fast as the native du, but much more useful. It sorts by size, and allows quick navigation up and down through the file tree.

It's much easier to parse when trying to answer the question "what the hell is taking up so much space, and where is it?" than using du.

Much simpler way to find where the space on your disk is being used.

It's incredibly fast and easy to use (if you are used with the terminal)
