6. Accessing the File System from Node.js
Interacting with the file system in Node.js is extremely important, especially if you need to manage dynamic files to support a web application or service. Node.js provides a good interface for interacting with the file system in the fs module. This module provides the standard file access APIs that are available in most languages to open, read, write, and interact with files.

You will also be able to access file and folder information and delete, truncate, and rename files and folders.
