File system
Introduction
Even though Mobi Builder applications are based off HTML, CSS and JavaScript (the three main programming languages used when creating websites (this does not mean that your applications will need an internet connection to work)), Mobi Builder applications do support some native functionality, like the file system. In this tutorial, you will learn how to use the file system in your Mobi Builder application. This can allow you to store user data locally on the users device. For example, this may be useful in a notepad editor where the users notes need to be saved so that the users can come back to their notes later. If you need to save data on the cloud so that multiple users can access this data, we recommend that you use firebase cloud.
Important note
Files created using the Mobi Builder file system blocks are only accessible by your application. Users can't access them.
