There is only one version of the Dropbox client, and its functionality is the same for all users. However, the cloud nature of the service makes it necessary for Dropbox to charge users who need a lot of storage space.

There are currently three Dropbox plans: the free plan, which offers two gigabytes of storage space; the Pro plan, which offers 100 gigabytes of storage and is priced at $9.99 per month; and the Business Plan, which predictably offers unlimited space for 5 or more users and is priced at $15 per month.
