Still getting use to using Dropbox, so hopefully not to much of a silly question. When I go to delete a "on-line file only" to save hard drive space, it states 'delete everywhere' does this mean the file can no longer be opened/viewed to the person I have previously sent it to? I've been using Dropbox for about 2.5 years, but I have to keep my files for a minimum of 5 years. So if I delete everywhere does this mean no-one can view that file again?
