I bought the new PDF expert app, and both have dropbox synced to them. I want to delete the dropbox folder synced to my old PDF expert app, but I am afraid that if I do it, I will end up deleting all my files when I open up the dropbox app. How can I delete the dropbox folder in my old PDF expert file without deleting any files in dropbox or the new PDF expert? Having duplicate files is taking up a lot of space...
