Virtually every Windows Phone- and mobility-oriented web site and blog is publishing information about how to access the storage on your Windows Phone from a Windows PC as if it were a normal mass storage device. Some are even recommending this practice.
Please listen very carefully. Do not do this.
Microsoft very specifically designed Windows Phone not to be used in this way. The software giant is no stranger to mass storage, obviously, and if this wasn’t going to cause problems, they would of course have designed Windows Phone otherwise.
Here’s what Microsoft corporate vice president Joe Belfiore said to me on this topic the day after the Windows Phone 7 launch event in New York late last month:
“Windows Phone is not a mass storage device. It’s a Zune device. The data on the phone must be consistent, and [the system] needs to be able to identify items in storage. We don’t want the user to have to do that stuff manually. Yes, some may want to. But we wanted a synchronization system that was simple and easy and does metadata mappings automatically.”
