Research In Motion has signed a patent licensing agreement with Microsoft Corp. to use the software company's latest file system technology on its smartphones.

Financial terms of the deal were not immediately available.

The agreement gives RIM access to the latest Extended File Allocation Table technology, which makes the handling of large files easier.

Microsoft says the new system expands the size of files that flash memory devices can handle and increases the speed with which those files can be accessed.

The deal comes as RIM works to launch the next generation of its BlackBerry smartphones.

The company's future is riding on the success of its BlackBerry 10 operating system and new phones expected early next year.
