The Dropbox client acts as a bridge between you and the files stored on the cloud servers. You download the application from its official website and install it. Log-in with the username and password that you created. After this procedure, select a local folder that will act as a mirror for the cloud service. Once you accept all the changes and set the application, the client will automatically add all the files from the cloud storage to the computer where the client is installed. Every action you do on your computer in that folder, will automatically replicate for the cloud storage as well (eg. you delete a file from a folder, then on the cloud the file will be deleted as well ). Once you add a file in the synchronized folder, then that file will be uploaded on the cloud servers, then you access it from everywhere (mobile device, web browser, etc).
