The software looks brilliant and works really well. As a bonus, as well as allowing you to chose what to sync, it also allows you to enable to encryption on the files, so no one would be able to view them apart from you, even if your Dropbox account became compromised.
What if I don't use Dropbox?Well, not to worry! Immortal Files also works with Google Drive, so you can have the best of both worlds.
