What function is responsible for storing and organizing a user's work in computer files?

The function responsible for storing and organizing a user's work in computer files is the File Manager. A File Manager is a tool that provides a user interface to manage files and folders on the computer. It allows users to create, delete, move, rename, and organize files into directories, making it easy to find and access different pieces of work efficiently. This is essential for maintaining an organized workspace and ensuring that important documents are easily retrievable.

In contrast, the Task Manager monitors the performance of various running applications and system processes rather than handling file organization. The Control Panel is primarily used for configuring system settings and hardware devices, which does not focus on file storage or organization. Disk Utility is focused on managing disk drives, such as formatting and repairing them, rather than organizing files and folders for a user. Thus, the File Manager is crucial for any user looking to keep their work organized within the file system.
