what is the best disk space explorer utility for linux?

I want to see folder wise size graphically, which folder has taken how much disk space.

  • Not to be too pedantic but disk space and file usage can be quite different. Baobab, one of the answers, shows files under the root '/' and has no concept of multiple disks or free space. Something like gparted is good at showing overall disk stats but is useless for lower level detail. WinDirStat, and I assume KDirStat, show both disk based and file based information. – AnnanFay Apr 6 '15 at 12:54

Personally I like KDirStat.

  • Does the job ^-^. Running on gnome desktop the application used its KDE standards instead of trying to use my gnome equivalents. Though whadayaexpect. Great app for the job so long as Baobab doesn't add individual file visualization support. – ThorSummoner Oct 15 '14 at 23:29

    Would be perfect, if it didn't want a hundred or two megs of KDE dependencies, not so good if you're not on KDE & don't want all it's stuff, generally counterproductive to increase disk usage that much while trying to reduce disk usage – Xen2050 Jul 13 '15 at 13:53

    It has been superseded by QDirStat, which does not depend on KDE. – Chris Hunt Jan 26 '19 at 16:35

    Also called Baobab. – Mechanical snail Jul 3 '12 at 6:46
  • baobab is awesome! (I wish it had the "delete permanently" option in addition to "move to trash") – pwned Apr 23 '17 at 18:53
  • baobab is painfully slow (unless you have <100k files and lots of time), qdirstat seems to work much better for me. – Mygod May 14 '19 at 13:15

TreeSize for Unix

Filelight (KDE)

xdiskusage

While not the prettiest, ncdu works in a text-only terminal and does provide a simple graph of each entry.

Not at all graphical, but highly useful: gt5

    +1 for ncdu, it's very useful when connected to machines via ssh. – Matthias Braun Mar 14 '17 at 16:49
  • Awesome tool, but xdiskusage and specially ncdu – Anwar Oct 28 '17 at 16:40
