File management

File management in an operating system (OS) involves organizing a computer's files and programs into a hierarchy of directories. The OS also manages the storage of these files on secondary devices like hard disk drives and solid-state drives. 

• Here are some functions of file management in an OS: 

• File creation: Allocates storage for new files.
• File access: Allows users to read, write, and execute files, while also enforcing access permissions
• File modification: Allows users to edit, update, or delete files 
• File organization: Maintains the file hierarchy and provides directory management 
• File details: Provides information about files, such as their location, owner, creation time, and type.

A file manager is a key component of an OS that organizes files into directories, folders, and sub-folders. It also provides a graphical interface to make it easier to find and navigate files. Some common functions of a file manager include:

Save, Search, Open, Delete, Rename, and Copy.
