Utility software is a kind of system software designed to help analyze, configure, optimize and maintain the computer.

Most utilities are highly specialized and designed to perform only a single task or small range of tasks.

Utility software categories

• Disk storage utilities
  Disk defragmenters can detect computer files whose contents are broken across several locations on the hard disk, and move the fragments to one location to increase efficiency.
  
  
• Disk checkers
  scans the contents of a hard disk to find files or areas that are corrupted in some way, or were not correctly saved, and eliminate them for a more efficiently operating hard drive.
  
  
• Disk cleaners
  finds files that are unnecessary to computer operation, or take up considerable amounts of space. Disk cleaner helps the user to decide what to delete when their hard disk is full.
  
  
• Disk space analyzers for the visualization of disk space usage by getting the size for each folder (including sub folders) & files in folder or drive. showing the distribution of the used space.
  
  
• Disk partitions
  can divide an individual drive into multiple logical drives, each with its own file system which can be mounted by the operating system and treated as an individual drive.
  
  
• Backup utilities
  can make a copy of all information stored on a disk, and restore either the entire disk (e.g. in an event of disk failure) or selected files (e.g. in an event of accidental deletion).
  
  
• Disk compression
  utilities can transparently compress/uncompress the contents of a disk, increasing the capacity of the disk.
  
  
• File managers
  provide a convenient method of performing routine data management tasks, such as deleting, renaming, cataloging, uncataloging, moving, copying, merging, generating and modifying data sets.
  
  
• Archive utilities
  output a stream or a single file when provided with a directory or a set of files. Archive utilities, unlike archive suites, usually do not include compression or encryption capabilities. Some archive utilities may even have a separate un-archive utility for the reverse operation.
  
  
• System profilers
  provide detailed information about the software installed and hardware attached to the computer.
  
  
• Anti-virus utilities
  scan for computer viruses.
  
  
• Hex editors
  directly modify the text or data of a file. These files could be data or an actual program.
  
  
• Data compression
  utilities output a shorter stream or a smaller file when provided with a stream or file.
  
  
• Cryptographic utilities
  encrypt and decrypt streams and files.
  
  
• Registry cleaners
  clean and optimize the Windows registry by removing old registry keys that are no longer in use.
  
  
• Network utilities
  analyze the computer's network connectivity, configure network settings, check data transfer or log events.
  
  
• Command line interface (CLI) and Graphical user interface (GUI)
  Allows the user to contact and make changes to the operating system.
  
  
• Screensavers
  prevents phosphor burn-in on CRT and plasma computer monitors by blanking the screen or filling it with moving images or patterns when the computer is not in use. Contemporary screensavers are used primarily for entertainment or security
