Dropbox

Dropbox is a Web-based file hosting service operated by Dropbox, Inc. that uses cloud computing to enable users to store and share files and folders with others across the Internet using file synchronization.

There are both free and paid services, each with varying options.

Dropbox offers a relatively large number of user clients across a variety of desktop and mobile operating systems.

The Dropbox client enables users to drop any file into a designated folder that is then synced with Dropbox's Internet service and to any other of the user's computers and devices with the Dropbox client.
