I have had my iPad for about a month. I got it mainly to keep all of my sheet music on it for gigs instead of carrying a bunch of heavy books. So far I am really enjoying it. I want to create a folder to keep some PDFs for my work on it and can't figure it out. I would then like to take these PDFs that I have uploaded from my pc to Dropbox and then store them in the folder I have made. So I need to find out how to do these 2 things
