Microsoft announced today that it supports the inclusion of its exFAT (Extended File Allocation Table) file system for USB flash drives and SD cards in the Linux kernel. ExFAT was introduced more than a decade ago in 2006 as the successor to FAT32 in the FAT family of file systems. Microsoft joined The Linux Foundation as a platinum member in November 2016 after slowly embracing the open-source software model after Satya Nadella took over as the company’s CEO. Microsoft also developed the Windows Subsystem for Linux, a compatibility layer that makes it possible for users of Windows 10 and Windows Server 2019 to natively run Linux binaries in ELF format on their computers.
