Spotmau Partition Genius interface is composed of an action panel, a menu bar, toolbar, a disk map, a partition list, and an operation queue. You can display/hide or resize different parts of the interface to operate the Partition Genius.

In the Partition Genius main window, the menu bar and a toolbar appear at the top of the window. The menu bar gives you access to all of Partition Genius features.
The disk map shows the partitions graphically and to approximate scale. (You can also scale the disk map display by clicking View > Scale Disk Map.) Each partition is represented by a different color according to the file system it uses.
If the selected hard disk contains logical partitions, the logical partitions are shown within an extended partition. The disk map will also show unallocated space (space that is not assigned to any partition) as a solid dark gray block (see image below).
