GParted is a free, graphical partition editor that you can use to resize, copy, and move partitions without data loss or file corruption. You may want to shrink a partition to create space for another operating system or a backup partition. GParted is part of many other hard disk tools, such as Clonezilla or Partclone. It can also be downloaded from the official website as a small bootable GNU/Linux distribution for x86 based computers and used from a USB flash drive.
