Differentiate between the types and usage of utility programs (file management, diagnostic and file compression).

File Management

Usage: File management is a utility program that performs functions related to files and disk management.

It provides functions to delete, copy. move, rename and view files as well as create and manage folders (directories).

File manager performs tasks of formatting and copying disks, displaying a list of files on a storage medium, checking the amount of used or free space on a storage medium, organising, copying, renaming, deleting, moving and sorting files and also creating shortcuts.

Example: Windows Explorer

Diagnostic

Usage :A diagnostic utility compiles technical information about a computer's hardware and certain system software programs and then prepares a report outlining any identified problems. Information in the report assists technical support staff in remedying any problems.

Example: Norton Utilities

File Compression

Usage: A file compression software that we use to shrink the size of files so they require less storage space and reduce transmission time if we send them over the internet.

Example: WinZip, WinRar, PKZip
