Dropbox

FREE (2GB) www.dropbox.com

Dropbox is great for storing pretty much any digital file type. Organising files is a cinch thanks to the intuitive folder system, plus you can access your files on the go with apps for iOS, Android and Blackberry mobile devices.

All this and 2GB of storage is free with a Dropbox Basic account. A Pro account offers 1TB for £7.99/ $9.99 a month or £79/$99.99 a year, or you can get an extra 500MB of space for referring a friend.

For its versatility and simplicity, Dropbox is superb, but ultimately Flickr’s more attractive interface, social interaction and sheer value make it the better option.
