What is GParted?
GParted is a GTK+ frontend to GNU Parted and the official GNOME Partition Editor application. It is used for creating, deleting, resizing, moving, checking and copying partitions, and the file systems 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).
GParted is developed on GNU/Linux. It can be used on other operating systems, such as Windows or Mac OS X, by booting from media containing GParted Live, which can be installed on CD, USB, PXE server, and Hard Disk then run on an x86 machine.
The bootable image is called GParted Live and enables all the features of the GParted application.
