I have shared files and folder with friends and family and after time passes they sometimes delete or move them and delete the folder. The problem is that I have lost some very important stuff because it removes them from my computer and dropbox.com. I even tried it in the Family Room which is I assume for sharing family photos. Any mistake by a shred person that my accidently delete a photo, the whole family will loose it. I have searched the help center and it seems to be the case because there is no good explanation for this simple problem. I would have to make duplicates of everything before I share it.
