Access to the core of your smartphone is one of Android's core strengths against its competition; not only does this make it simpler to tweak, it also makes it possible to simply shift files around at will. ASTRO File Manager makes it even easier again.
It's pretty rare that you can say that a file manager actually looks good; functionality is usually the core criteria. But ASTRO does look good with nicely rounded icons and a sleek UI that responds quickly and makes basic file tasks a breeze. It's also got Honeycomb support for Android tablet users with its own distinct UI. Best of all, like many Android apps, it won't cost you a cent. [ASTRO File Manager]
