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)
