Box.net Files (OpenBox Services for Facebook and LinkedIn)
Social networks are great at lots of things, such as putting you in touch and letting you share web links, videos, and photos. But they're not ideal places to store and share documents and files - unless you have Box.net's OpenBox Services for Facebook and LinkedIn, that is. These free apps turn either social network into something of a virtual thumb drive, one that's easy to share with friends. You can easily upload files or create folders. You can share single documents or entire folders with your social network contacts - and if you're signed up for both the Facebook and LinkedIn versions, you can share across social networks, too. You get 5GB of storage and the ability to upload files as big as 25MB with a free personal account; paid personal accounts with more storage start at $10 (£6) per month. Business versions, which add some searching and security features, such as the ability to assign user privileges to files, start at $15 (9) per month.
