I am repeating a portion of one of my comments here because I think it could be very useful to many Dropbox users. If you implement this tonight you will, effectively, isolate your local data from Dropbox and any accidental loss at Dropbox will not result in total loss locally. Of course, you are responsible for local backups. If this gets up-voted to the top of the thread it might just help a lot of people avoid accidental loss of valuable data. My approach for Dropbox on both Windows and OSX is to have the Dropbox folder on a dedicated drive partition. If that is not possible, you can use a drive that will never see development work or any data that will need to be shared via Dropbox (business data, kid's pictures, etc.). This forces a FILE COPY operation rather than a FILE MOVE operation when you drag-and-drop files into any Dropbox folder. Which, in turn, means that everything in Dropbox could be trashed tomorrow and nothing whatsoever would be lost locally. For years I have gotten in the habit of having at least two physical drives on every machine: System and Data. If I don't want to create a dedicated Dropbox partition I can usually place my Dropbox folder in the System drive and this will trigger copy-on-drag-and-drop whenever dragging files in from the Data drive. If you don't have separate physical System and Data drives (highly recommended) you can split a single drive into System and Data partitions or simply split-off a Dropbox partition in order to achieve the same results. DROPBOX FEATURE REQUEST: It would be very nice if the Dropbox client software could have an option to auto-magically COPY files in and out of Dropbox rather than allowing any files to be moved.
