Okay so let me start off with "I'm a Android newb". Now on to the question. I dowloaded Astro to get ready for my movie and music downloading onslaught. Now on the main screen when you pull up the app I have AMAZONmp3 as one of the main files, is this normal? And I'm no computer whiz but it seems like there is a lot of superfluous files and garbage that I could do without. So before I start deleting, are some of these files necessary? I mean the AMAZON file has a cache file with like a couple hundred images that i absolutely dont know where they came from. Thanks for any insight.
