Now I am slightly new to the android game. Had a D1 that I traded for and I loved it. Used Astro File manager on there to get swype when it was available. I hear about this app and how it is great and you need it. I have downloaded it and I am not really 100% positive on its purpose. Is it just an easy way to delete files? Are there files I shouldnt delete? I am not rooted (I'd like to be but I am a big chicken).
