However, those files will no longer appear in the Dropbox folder on your computer. Selective sync also helps you save hard drive space by removing files from your hard drive so that they’re online-only. When you open an online-only file, Dropbox automatically makes it available offline again, but you can change it back to online-only at any time. Dropbox removes this file or folder from your computer’s hard drive, so that it only takes up space in your Dropbox account online. You can only open it if you’re connected to the Internet. If you set a file or folder to online-only, you’ll still see the file or folder in the Dropbox folder on your computer, but it’s just a placeholder. This means that they take up space both on your computer’s hard drive and in your Dropbox account, but are available even when you’re not connected to the Internet. If you haven’t set a file or folder to online-only, then all files and folders in the Dropbox folder on your computer are available offline.
