The move function is used to physically move a partition on the
disk. At present, only primary partitions can be moved in this way.
To move a partition, there must be empty space adjacent to it in the direction
you want to move. To move a partition you must first select it in either
the partition diagram or the
partition list (when the selected item is empty space, this
disabled). Before moving any partition, you must commit any outstanding
changes using the write changes function, or else
undo your changes using the undo function. Once
a move commences the data is physically moved on disk, so you cannot
subsequently use the undo function to reverse the move
(rather, you would have to move the partition back again). A move
operation can take a considerable time to complete, and is quite invasive.
Backing up all important data is strongly encouraged.
