I just now set up Dropbox on a new Windows 10 laptop. I made the target folder C:\Dropbox. But then I realized that was a stupid idea, and I moved the files to C:\A\Dropbox, which is a much better location for my Dropbox folder. Now Dropbox won't even open. It gives me that "Dropbox Folder Missing" error ("Your Dropbox folder has been moved or deleted..."). What on earth am I supposed to do? This doesn't make any sense.
