I am a relative newbie to this forum, so forgive me if this has been asked a million times. I have an Incredible, and need to know which files are safe to rename, move, and manipulate. For instance, I want to move my music, pictures, and other media around, and rename the folders so their easier to recognize, but I don't know this system like I do Windows. Can you rename, create, and move folders without ruining the functionality of the phone? Thanks!
