What is Ubuntu's version of Disk Management?

Question

I need to find out because I need to see my hard drive space on my laptop.

Answer 1

For a more "Disk management" -style display, do

$ upd sudo apt install gparted
to install the gnu partition editor from a terminal.

then run it, also from the terminal by

$ sudo gparted

... or; hit Win/Super key and type gparted (possibly drag the icon to the dash) and click on the icon (it will ask for root access, type your password).

Answer 2

Not Ubuntu version specifically, but Filelight (https://packages.ubuntu.com/noble/filelight) shows disk usage in a pretty neat format, see in link: https://apps.kde.org/filelight/

Edit after @FedKad, Gnome version is https://packages.ubuntu.com/noble/baobab
