GParted is an Open Source live app for creating, destroying, resizing, moving, checking, and copying partitions and the file systems on them.
A hard disk is usually subdivided into one or more partitions. These partitions typically are not re-sizable (making one smaller and the adjacent one larger). The purpose of GParted is to allow the individual to take a hard disk and change the partition organization therein while preserving the partition contents.
GParted 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 uses GNU libparted to detect and manipulate devices and partition tables.
Several (optional) file system tools provide support for file systems not included in libparted. These optional packages will be detected at runtime and do not require a rebuild of GParted.
