Adding photos and videos to Dropbox folder on Mac is easy. To do so, download and install 'Dropbox Desktop Application' on your Mac. Once you have installed Dropbox on your computer it creates a special folder (Dropbox folder) on your computer for storing the photos and videos. If you are a Dropbox for Business user and have connected your personal and work accounts, then it will create two separate folders. The Dropbox folder works just like any other folder on your hard drive. Anything you add into the Dropbox folder will automatically sync to the web and to any other computer with Dropbox installed.
You can use Drag-and-Drop feature to add photos and videos to Dropbox. You can simply drag your photos and videos directly from your Mac to a location in your Dropbox folder. The photos and videos in your Dropbox folder will automatically be synced online and to other computers.
