I have several DropBox folders on my desktop computer - Dropbox, Dropbox (Old), Dropbox (Old (1)), Dropbox (Old (2)). I don't know how this happened. I tried deleting some but lost my desktop icons and had to resore them all back to square one! With all these duplicate folders I don't know where my files are being copied to. How can I rationalise my DropBox setup, please?
