Dropbox is a free online service that lets users store or access personal or shared photos, documents and videos from anywhere and share them easily.
Every document stored is automatically private, therefore, a user can control who can see what.
The documents, photos and vidoes are stored online and therefore can be accessed anywhere from phones to computers and tablets.
Dropbox has an automated backup system that stores files and documents online and therefore there is no hazard of losing them if a phone is lost or a computer has crashed.
Initially, the free Dropbox offers users 2GB of storage, but the space can be increased upto 16GB more by referring Dropbox to friends.
Dropbox can be upgraded via payment and the storage capacity can be expanded upto 32GB.
