Disk Utilities are software tools designed to manage and maintain computer storage devices, such as hard drives and solid-state drives. They help users perform tasks like formatting, partitioning, and checking the health of disks. These utilities can also recover lost data and optimize disk performance, ensuring that the storage operates efficiently. Common features of Disk Utilities include disk cleanup, which removes unnecessary files, and disk defragmentation, which reorganizes fragmented data for faster access. Many operating systems, like Windows and macOS, come with built-in Disk Utilities, while third-party options are also available for more advanced functionalities.
