Chapter 5: File System Access - Reading, Writing, and Managing Data

Welcome back, future Puter.js masters! In our previous chapters, we laid the groundwork by understanding what Puter.js is and how to interact with its core APIs. Now, it’s time to make our applications truly useful by giving them memory: the ability to store and retrieve data.

In this chapter, we’ll dive deep into the Puter.js File System. This is where your applications can read configuration files, save user preferences, store game progress, or even manage complex application-specific data. We’ll learn how to perform essential file operations like reading content, writing new data, creating and listing directories, and even cleaning up files and folders. By the end of this chapter, you’ll be able to equip your Puter.js apps with persistent storage, making them more dynamic and user-friendly. Ready to give your apps a memory? Let’s go!
