Selective Sync is a feature of the Dropbox desktop application that allows you to select only the folders you want to be synced to your computer. Selective Sync gives you the control to ensure you have only the files you need on any computer. It’s especially handy if you want to save space on netbooks and other computers with small hard drives.

To enable Selective Sync, head to your Dropbox preferences from your desktop:

STEP 1.  Click on the Dropbox icon from the system tray

STEP 2.  Click on the gear icon and select Preferences… from the menu

STEP 3.  Click the Account tab

Dropbox Business users: If you have connected your personal and work Dropboxes, you’ll also need to select the Dropbox for which you want to change settings at the top of the tab.

STEP 4.  Click the Selective Sync… button

STEP 5.  A window will appear with a list of all the top level folders in your Dropbox folder.

The folders with a check next to them will be synced to your computer. Uncheck any folders that you don’t need to sync to your computer’s hard drive.

STEP 6.  When you are done, select OK.

Any folders you deselected will be removed from your hard drive, but will still be available through the website and on any computers linked to your Dropbox account.
