From the developer:
Quicksand makes the cloud simple: it's a free Mac app that syncs all the files you've been working on recently with your favorite cloud storage solution, so you don't need to plan ahead.
Every time you open a file, Quicksand auto-syncs it to the cloud, so that you’ll always have access to the files you’ve been working on recently, wherever you are, whenever you need them.
