GParted is the Gnome Partition Editor application. GParted is an industrial-strength package for creating, destroying, resizing, moving, checking, and copying partitions, and the filesystems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks and mirroring one partition with another (disk imaging).
It is important to remember that all partitions must be unmounted before you can modify any of them. Because of this, it is usually easy to use the GParted Live-CD instead of the GUI desktop app. Download the latest Live-CD version, burn it to a disc, and then boot from this disk. The steps involved after that are extremely user-friendly.
GParted supports the following filesystems: ext2, ext3, fat16, fat32, hfs, hfs+, jfs, linux-swap, reiserfs, reiser4, ufs, xfs, and even ntfs (Windows).
