Dropbox is a secure hosting service which enables users to synchronize files automatically between multiple computers and mobile devices. A change made to a file on one computer will be nearly immediately updated online and on other computers and mobile devices linked to the Dropbox folder. This is by far the easiest way to share files and folders across desktops, laptops, computer tablets and smart phones.
Dropbox service was founded in 2007 by MIT graduates Drew Houston and Arash Ferdowsi. The service uses SSL transfers for synchronization and stores data via AES-256 encryption. There are both free and paid services, each with varying options. The free service comes with 2 GB of free online storage.
Dropbox supports different versions of Microsoft Windows, Mac OS X, and Linux (official and unofficial), as well as versions of mobile devices, such as the iPhone, iPad, Android, and BlackBerry, and a web-based client for when no local client is installed. Dropbox has now an App for iPhone and iPod touch in the AppStore!
