Over on The Sweet Setup, Dropbox is smack in the middle of Mac apps we think you should be using.

And our senior editor, Jeff Abbott, wrote an excellent guide to using Dropbox. The guide covers the basics of how to get up and running, and it outlines how to get additional storage space for free. But it also covers expert-level tips such as syncing your application support files, setting up symlinks, integrating with 3rd-party services like IFTTT and Wufoo, and so much more.

There are also organization tips for how to best keep your synced files and folders free from chaos and clutter. Plus there are three bonus documents that cover photo sharing and how families can get the most out of Dropbox.

The guide is brand new, and this week it’s on sale for 25% off. Not to mention we’re bundling it with another great ebook by Bradley Chambers: Learning to Love Photo Management
