Fedora, ext4 filesystems are the most common. Typically you will want to own the filesystem, so allow the tick to remain in the check box labeled Take ownership of file system. If you want the filesystem to be encrypted, put a tick in the check box labeled Encrypt underlying filesystem. Finally, click Create. After checking with you, palimpsest will create the filesystem. If you did not use all of the free space, you can create additional partitions/filesystems in the same manner. From the

It describes several ways to launch objects (run programs) from the desktop, how to set up the desktop to meet your needs and please your senses, and how to manipulate windows. As the tour continues, it explains how to work with files and folders using the Nautilus File Browser window, one of the most important GNOME tools. The tour concludes with a discussion of the Update applet, the object that allows you to keep a system up-to-date
