I desire to keep one particular folder I use for college in sync with either service. It would be preferable if this folder would automatically sync at an interval, in order to keep updated and backed up. Is this at all possible? The folder would not be placed in either "dropbox" or "skydrive" folder, but simply backed up and replicated by either service. Is there a third party app that will do this, or perhaps a native solution for either app to accomplish this? Thanks!
