With 19 million downloads from the Android Market, it might be easy to get complacent. Not so in the case of ASTRO File Manager which today received an update to version 3.1, and brought a couple of big new features along with it.
The first of these are the new themes functionality, allowing you to download various different themes to customize the app with including the "classic ASTRO" theme from version 2.0.
The other big new feature is the ability to pre-register for a free ASTRO backup account. There's no further information at this stage on this part of the service, but registration is as simple as entering your email address from the splashscreen.
Other notable updates include Honeycomb support, various fixes, drag and drop capabilities and tablet users are now able to set the external SD and USB directories.
Check out a selection of screenshots along with the download links after the break.
