Ubuntu Linux includes a great Disk Usage Analyzer GUI tool that will let you figure out what files and folders are taking up all the space on your hard drive. This is one of those great little tools that should be bundled with every operating system.

You’ll find the tool on your Accessories menu:

When you start the tool,  you have a choice of opening the filesystem or a particular folder. If you choose filesystem, you will have to wait for a while because it’s going through and checking all the files and folders on your system… but it’s worth the wait when you see the nice GUI in action:

Right click on anything in the tree, and you will see a list of options:

Open will obviously open that folder with Gnome’s file browser. List all files in folder will show you the list right in the tool.

The folder graphical map seems like a nice idea, but as of this howto, doesn’t look like it tells you the name of the file/folder in the map. I’m sure that will be resolved soon.

You can also delete files from within the tool, which is an added plus.

Tested on: Ubuntu Edgy Eft. (Tool may not exist on prior versions)
