I did a uninstall and a reinstall as some shared files were not going into Dropbox. When I did the reinstall it looks like it is syncing absolutely everything on my computer. I also have a file called Dropbox (old) which I thought would be removed. In the new Dropbox file, I have folders but nothing is in them. I don't know how to resolve this . I cannot find the tabs that the instructions on the website are eluding to. Please help.
