Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning allows the use of different filesystems to be installed for different kinds of files. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. Each partition then appears to the operating system as a distinct 'logical' disk that uses part of the actual disk. The disk stores the information about the partitions' locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. It is typically the first step of preparing a newly installed disk, before any file system is created.
