How can one access system files on an Android device?

You can access system files on an Android device by opening a secret drawer inside your phone.

Imagine your phone is like a toy box, it has all sorts of toys (apps) and tools (files). Most of the time, you just play with the toys. But sometimes, you want to see what's inside the toy box or even take out some tools to build something new.

To open this secret drawer, you need a special key, it’s called Developer Options. To get there, go to your phone’s Settings, then tap on About Phone and tap Build Number seven times (like tapping a magic number). After that, go back to Settings, and the secret drawer (Developer Options) will appear.

Once you're in, turn on USB Debugging, it's like giving your phone a tiny helper who can carry files from the toy box to your computer. Then connect your phone to a computer with a cable (like connecting two friends), and now you can see all those hidden tools (system files) and even move them around!
