Disk partitioning is the creation of separate ivisions of a hard disk. Once a disk is divided into several partitions, directories and files of different categories may be stored in different partitions. More partitions provide more control but too many become cumbersome. The way space management, access permissions and directory searching are implemented depends upon the type of file system installed on a partition. Careful consideration of the size of the partition is necessary as the ability to change the size depends on the file system installed on the partition.
