GParted (GNOME Partition Editor) is a GUI tool for managing disk partitions. It handles create, resize, move, and delete operations without using the terminal. If you already know how to use mkdir in Linux or how to use the locate command in Linux, this fits naturally into your workflow.
It supports common file systems: ext4, NTFS, FAT32, XFS, Btrfs. Works well in mixed Linux/Windows setups. It pairs well with essential systemd commands in Linux when preparing systems before disk changes.
Run it in live mode to modify system partitions safely. No mounted disks. Fewer risks.
