Today almost everyone have more than one computer; one at work, a few at home, a media center, a PC, a Mac etc, your family members, friends and colleagues have the same. One problem is that a lot of us need access to files on one machine when we are using one of the others. For example I want to access my images when I’m at work sometimes and I do not want to copy all of these images onto my work laptop, when I’m at home I want to have the same favorites and documents that I use at work and so on.
