Dropbox Smart Sync allows you to free up hard drive space on your computer by moving files and folders to the cloud (online-only).
Files and folders stored with Smart Sync will appear in the Dropbox folder on your computer, in the Dropbox mobile app, and on dropbox.com for easy file management. When you need to access a file that is stored with Smart Sync, just double-click it and Dropbox quickly downloads and opens it for you.
Smart Sync can also help you save space automatically, by identifying infrequently used files and folders and moving them to the cloud.
While your admin can choose default sync settings for the team, you can always enable Smart Sync for specific files and folders and choose to make them local or online-only. With Smart Sync and other features like selective sync, spend less time managing your storage space and more time doing work that matters.
Open a file as usual through the Dropbox desktop app, its native application, Finder (Mac), or Windows Explorer. Dropbox instantly downloads the file to your computer. This file will continue to be synced to your Dropbox account, but it will also use space on your hard drive.
Selective sync is another Dropbox feature that allows you to choose which files to remove from your hard drive. You’ll still be able to access them on dropbox.com, but they won’t appear on your computer. Selective sync helps you free up hard drive space without deleting anything from your Dropbox account.
