Dropbox is a file hosting service that includes cloud storage, personal cloud, file synchronization, and client software across multiple platforms. Dropbox allows users to create a folder on each of their computers where any type of file can be saved, synchronized, and made available across all computers. Contents of the Dropbox folder are also accessible via dropbox.com and mobile applications. Individual files and folders can be shared with other Dropbox users or made publicly accessible.

Dropbox for Business is a paid service targeting organizations by providing administrative controls and auditing functionality while allowing users to create a work account that is completely separate from their personal account but the two are viewable side by side.
