Box.net has been around for quite a while, but is still one of our favorite places to store documents online. Thanks to its integration with numerous online services, including Gmail, Zoho, picnick, and Scribd, box.net can not only store all your documents, but can also function as the hub of your virtual office.
One other nice feature of box.net is that you can share your files and folders with ‘collaborators,’ which makes it a good service to exchange files within a small business or among friends.
The storage limit for the free accounts is 1GB, which is plenty if you mostly exchange text documents or spreadsheets. Paid accounts start at $7.95 a month and include more advanced features, including 5GB of storage, a versioning system, mobile access, and 24/7 phone support.
