Which task is performed by the operating system to manage files?

• A. Naming, saving, moving, and deleting files
• B. Defragmentation of files
• C. Backing up files to cloud
• D. Editing images

Answer: (A)

File management tasks involve giving each file a name and a place to live, saving data, moving it within directories, and deleting it when needed. The operating system provides the filesystem, translates user paths into physical locations, and handles requests to create, open, read/write, rename, move, or remove files. It also maintains metadata (size, timestamps, permissions) and enforces access controls so only authorized users can operate on files. That description matches what the OS does for everyday file handling, making it the best choice. The other options describe maintenance or application-level activities: defragmentation optimizes disk layout, cloud backups protect data, and image editing is done by applications, not by the OS’s file-management duties.
