GParted stands for Gnome Partition Editor. Among other features it supports creating, resizing, moving and copying of partitions.

New Features:
* Detailed progressfeedback. Every step of an operation will be
described to the user. Because all this info is stored in a treeview
you can choose how many details you like to see.
* it's now possible to cancel a running operation.
* run a resize-simulation before performing the actual resize (only
for NTFS)
