We've learned many file manipulation techniques throughout our exploration of the FileSystem (fs) module. But directories are more than places to store files - they offer opportunities for organization, data analysis, and more.

In this chapter, we'll dive into directory manipulation and guide you on navigating directories, gathering vital statistics, processing directories, and creating a script to analyze and display directory contents.

📂 Navigating Directories with fs.readdir

The fs.readdir method asynchronously reads the contents of a directory. It returns an array of filenames. This method can be beneficial for task listing files in a folder.

Consider a scenario where we deal with extensive legal contracts, briefs, and other documents related to different cases and clients. We could create a system that extracts and lists the names of the files within each client's folder.

Code Example: Read the file names of a directory

📊 Obtaining Directories Statistics with fs.stat

Directories house files and hold valuable information about each file's attributes.

The fs.stat method asynchronously retrieves the stats of a file or directory. These stats include file size, permissions, timestamps, and more.

Let's obtain the statistics of each folder inside the docs folder.
