Smart Sync is a feature of the Dropbox desktop app that makes files online-only so you can save hard drive space on your computer. You can choose which files to make online-only or let automatic Smart Sync choose for you.
Note: The Smart Sync preferences you choose are unique to each computer and don’t affect other computers you use with Dropbox.
Note: You must install the Dropbox desktop application to use Smart Sync.
To set a file or folder to online-only using Smart Sync:
If you set a file or folder to online-only, it is removed from your hard drive so that it’s only stored in your account on dropbox.com. You can still see the file or folder on your computer, but it’s just a placeholder. You need to be connected to the internet to open it. If you open the file, it becomes local and saves back to your computer’s hard drive. If you move, delete, or re-name it on your computer, even while offline, those changes will be mirrored on dropbox.com once your device is back online.
Selective sync also helps you save hard drive space by removing files from your hard drive so that they’re only saved on dropbox.com. However, you won’t be able to see those files or folders on your computer at all and there’s no automatic option for selective sync.
You can turn on automatic Smart Sync so that files you don’t open from your computer for a few months become online-only automatically and new files you add to dropbox.com become online-only by default.
To turn on automatic Smart Sync:
If you don’t open a file or folder from your computer for a few months, it’ll become online-only to save you hard drive space. If an application on your computer needs a file to be local to function properly, automatic Smart Sync will set it to local temporarily and return it to online-only later.
You can make all files that you add to dropbox.com online-only by default in two ways:
Online-only files take up a small amount of space on your hard drive because the placeholder requires space to store the file name and the shortcut to dropbox.com, but it takes up much less space than the file itself would.
Note: On Mac, online-only files may appear to take up the full amount of space. To fix this, follow the instructions in the “Set online-only files to zero ‘logical’ size” section of this article.
Mac: OS X Mavericks (10.9)
Windows: 7 and up
Note: You can’t use Smart Sync on a mobile device, but you can set your Dropbox files to open on your mobile device while you’re offline.
