I use Dropbox on my Windows 7, OS X and on my mobile phone. Sometimes I see a file called
.dropbox in my dropbox folders, can those files be deleted?

So, if you want to keep it shared, keep it - if you don't, you can remove it.
Note that moving a shared folder implies that you move it within dropbox structure.
Also, they say that in previous version of dropbox there was a bug that .dropbox files existed in all directories, but that should've been fixed years ago.
