GParted

GParted (GNOME Partition Editor) is a free, open-source tool that allows users to manage and organize their computer's storage drives. It enables actions such as creating, deleting, resizing, and arranging partitions—sections of the drive used to store data or install operating systems—without losing information. It's useful for optimizing space, preparing drives for new installations, or troubleshooting storage issues. GParted runs from a bootable environment or live CD, providing a graphical interface that makes complex disk management tasks more accessible and safer for users with varying experience levels.
