Accessing the internal storage of an Android device can be done in several ways, whether you are a user looking to manage files or a developer working on Android applications. This guide will walk you through both user and developer methods for accessing internal storage on an Android device.

For Users:

Whether you are a user looking to manage files on your device or a developer testing your application, accessing internal storage can be a straightforward process. This guide covers the methods for both scenarios.
