I'm just not getting it. How do add files/folders to the android Dropbox? I've copied files and folders into the /sdcard/dropbox folder but they don't show up in the Dropbox app nor are they synched to my PC Dropbox. I don't see a way to paste into the app. In the Dropbox app I see "Upload" then "Add any file" but the only options are to add a photo, music or voice recorder file. I was hoping to use it to back up some ebooks and data files to my desktop.
