Microsoft is testing its "Live Mesh" cloud computing technology with US users.
The technology allows users to quickly access pictures, documents, video and other data stored across multiple machines in different locations.
Live Mesh uses the internet as a data hub, synchronising files across computers, phones and other devices.
Around 10,000 US testers will initially use the technology on Windows-based computers, but the beta testing will be extended to Apple PCs, mobile phones and other devices in the coming months, said Microsoft.

As well as allowing consumers to easily access and share information, Live Mesh could also be used by firms to easily distribute information to authorised users registered to the system.
The beta is expected to be extended to users outside the US before the end of the year.
