Microsoft Corp. and BMW have signed a patent licensing agreement that gives BMW broad access to the latest Extended File Allocation Table (exFAT). BMW will utilize exFAT technology to enhance the digital entertainment offerings in its line of automobiles.

exFAT is a modern file system from Microsoft that facilitates large files for audiovisual media and enables seamless data portability and an easy interchange between desktop PCs and other electronic devices. exFAT improves on its predecessor, the FAT system, and greatly expands the size of files that flash memory devices can handle by five times over previous FAT technology. It also increases the speed with which those files can be accessed.
