Which service allows users to create partitions and format disks in a computer system?

Disk Management is a service that enables users to create and manage disk partitions, as well as format disks. This functionality is essential for organizing storage on a computer. When a hard drive or SSD is first installed, it may not be configured for use; Disk Management provides the tools necessary to set up the drive, including partitioning it into different sections for better data organization and allocating file systems such as NTFS or FAT32 to allow the operating system to read and write data to the disk.

Using Disk Management, users can also expand or shrink existing partitions, which is critical when needing to adjust storage space for applications and data. This service effectively manages the physical drive on a system, providing users with a centralized way to handle their storage needs. Other services mentioned do involve storage in one way or another, but they do not provide direct functionality for creating partitions and formatting disks.
