Is there a way (or an extensions) to display disk usage/remaining disk space, in Linux file browsers (Nautilus/Thunar) like what happens in Windows when you open My Computer/PC. I know conky can do that, but what of mounted drives.

    Dolphin (default file manager in Kubuntu) shows disk usage by default. – Archisman Panigrahi Aug 9 at 10:50

Command line tools

  • There are several command line tools for this purpose, for example df -h and lsblk -f that display disk usage/remaining disk space for mounted partitions.

      xubuntu@xubuntu:~$ df -h

  • You can also [install and] use baobab, which displays disk usage/remaining disk space for mounted partitions. baobab has a graphical desktop environment.

    enter image description here

    But the main purpose of baobab is to show the disk usage by directories and files with graphics. So when you click on one of the partition icons, you may see the following view,

    enter image description here


  • You can also [install and] use gparted, which displays disk usage/remaining disk space for mounted as well as unmounted partitions. gparted has a graphical desktop environment.

    • Use the small box near the top right corner of the window in order to select which drive to look at.

    • Mounted partitions are indicated with a key icon, showing that they are locked for editing (but you can unmount them).

    enter image description here


  • Thunar has a 'status line' at the bottom of its window, where the free space in the displayed partition is displayed. But I have not found any display in Thunar, that displays the remaining space in all partitions at the same time.

    There is also gnome-usage which is similar to baobab. – BlueManCZ Aug 10 at 12:59

In Nautilus you just right-click on the white space inside the folder (or any folder icon) and choose "Properties". The last record in the popup dialogue window is "Free space".

enter image description here

If you do this in the root folder of the disk, you also get information about used space, total capacity and filesystem type.

I like Gnome disks. It lists all the drives it can find on the left-hand side (including USB drives), whether they are mounted or not. If you click on one of them, it shows the details on the right:

  • formatting, partitions
  • space used/available
  • if mounted, where
  • etc.
