Dropbox is a simple-to-use file synchronization utility that uses the cloud storage to sync files across multiple computers, whether they are Mac, Linux or Windows based. In fact, not only can you access your private or shared files from any computer where you’ve installed the Dropbox utility, you can also access them via a browser from any computer at all. Some handy uses of Dropbox include password synchronization with password tools such as Roboform, 1Password or KeePass. Or as storage for portable apps, instead of putting them on a thumb drive.
