Advanced Tools For full access to all features of the app you will need root rights on your device. However, even without them, this app can work like an ordinary file Manager, which is very useful for all users. If you have rights, the functionality becomes more wider. It not just gives you complete access control on all files, but also gives access to all functions, even those which were hidden for standard users. However, one should be careful, if you don't know what you're looking for, and start to change or delete files, it may affect your device.
