    Microsoft adding exFAT to Linux kernel


    Posted: 28 Aug 2019
    Microsoft ♥ Linux – we say that a lot, and we mean it! Today we’re pleased to announce that Microsoft is supporting the addition of Microsoft’s exFAT technology to the Linux kernel.

    exFAT is the Microsoft-developed file system that’s used in Windows and in many types of storage devices like SD Cards and USB flash drives. It’s why hundreds of millions of storage devices that are formatted using exFAT “just work” when you plug them into your laptop, camera, and car.

    It’s important to us that the Linux community can make use of exFAT included in the Linux kernel with confidence. To this end, we will be making Microsoft’s technical specification for exFAT publicly available to facilitate development of conformant, interoperable implementations. We also support the eventual inclusion of a Linux kernel with exFAT support in a future revision of the Open Invention Network’s Linux System Definition, where, once accepted, the code will benefit from the defensive patent commitments of OIN’s 3040+ members and licensees.

    For more information, please see the Microsoft technical specification for exFAT at https://docs.microsoft.com/windows/w...-specification.

    That is new. I dual-boot with Windows-10-pro & PCLinuxOS-kde.

    This must just of happened, because I see nothing of it on the Linux forums.

    Hi there
    Could be interesting -- however it would be nice if Windows could read and write to native Linux file systems too -- wouldn't it be great if Windows could read / write to XFS or REISER FS file systems without having to use file sharing protocols like SMB so you could attach a Linux formatted HDD directly to Windows and use it.

    Linux has been able to read / write to NTFS for donkeys years so even when proprietary file systems are discussed it has obviously been possible to "reverse engineer" a read / write system --the actual implementation in the Linux kernel is via "Fuse control" which can load file handling systems such as NTFS by package ntfs-3g - so by using an api from the "fuse" module in the kernel ntfs file systems can be handled.

    Windows should be able to have something like that -- it would need though perhaps to uncouple the I/O handler more than it is currently from the Windows kernel - which given the nature of Windows could potentially risk security problems -- anyway it's an interesting development for sure.

    I've been using Linux Mint for some time in a Desktop and a Notebook to format drives over 32GB as exFAT and still be usable on other OSes, have an exFAT 64GB thumb drive and a couple of USB HDDs at 500GB exFAT, gets around the single-file size limit of 4GB of FAT32. All the versions of Linux I've tried have included GPARTED, even their Bootable LiveDVD.

    Hi there
    Never had a problem on Fedora / Centos / other distros with exFAT and Micro sd cards either.

    I'm not sure I like the idea though of Ms being able to get its greasy mits on Linux kernels though -- at least not those used by most popular distros -- I prefer untainted kernels -- goodness knows what stuff Ms will introduce -- conspiracy theorists can surmise secret monitoring and "slow down" stuff to make sure its kernels don't run faster or more efficiently than Windows !!!

    GPARTED also works just fine on most live distros and has zillions of ways to format drives / thumbdrives / sd cards etc with all sorts of file systems and manipulate / re-arrange partitions too.

    I had a thought [yeah, that can be dangerous] and used Linux with GPARTED and reformatted a 500GB USB drive to FAT32, seems to be just fine on Windows.

    That is because exFAT drivers for linux have been available for years but adding them to the kernel is a positive sign from MS.
