File storage and sharing service Box released its first Windows Phone app this morning, rounding out its mobile offerings and looking to stand out in a sea of competition.

The app lets users view, move and share files on Windows Phone 7.5 devices. Features unique to Windows Phone include the ability to run slideshows of stored images and pin Live Tiles to the phone’s Start screen to be notified of updates.

In an attempt to appeal to its core business customers, Box offers the option for an app-specific passcode as an extra layer of security.

Box already has apps for iPhone, Android, and other mobile platforms. The company says in a blog post that 40 percent of its users are accessing the service from a mobile device.

In addition, the company announced a deal with Qualcomm to preload Box on “select Android and Windows devices” running Snapdragon processors.
