A shortcut to the native File Explorer available since Android 6.0 Marshmallow
As you may know, since Android 6.0 Marshmallow, Android introduced a file Explorer that allowed users to browse their internal storage's directories, open, copy and share files.
This feature is hidden in : Android's Settings > Storage > Explore
It's the reason why Magetys has build this app which is just a shortcut to the native File Explorer. No more reason to install third party File Explorer.
