To create a partition, right-click on the Unallocated Space (smaller rectangle with Free label) inside a disk and select Create partition
By default, the resulting partition will take the entire Unallocated Space area (between adjacent partitions and/or disk borders).
To set the resulting partition size, use Partition size slider or text field.
If you wish to change the resulting partition position, use Free space before and Free space after sliders.
If one of the Free Space sliders is engaged, moving the other Free Space slider will move the partition to Unallocated Space created using the first Free Space slider until there’s no Unallocated Space left on that side. Then the Free Space slider will shrink the partition.
Specify the File system and Volume name for the partition. If the resulting partition is too small, some file systems will be not listed.
If you don’t want to format the resulting partition, uncheck Format partition box.
Press OK. You can now preview your changes.
Press Apply operations, then – Apply.
