Once you install the Software from here, right-click on any folder or file and you will get an option under menu DropBox.
Any time you move a big size folder which will take time to upload and toll on your bandwidth, you can pause the syncing with just a right-click or use selective syncing where you can decide which folders should be synced. This feature helps you keep all required files in Dropbox folder and makes sure you don’t reach your Dropbox Storage limit.
