Microsoft Expands exFAT Multimedia Licensing

alphadogg writes "Microsoft Thursday announced a broadening of its licensing program around its exFAT file system, which is designed to handle large multimedia files. Microsoft hopes companies making devices such as cameras and smartphones will adopt the Extended File Allocation Table (exFAT) technology to support the sharing of audio and video files. The technology is available on Windows 7, Vista SP1, Windows Server 2008 and Windows Embedded CE."

      EEE only applies to open standard Microsoft targets.

      It also applies to Microsoft partners. The multi-media product manufacturers (including cameras, media players etc. etc.) will be the long term target. Right now their functionality is being extended with the aim of Microsoft getting lock in. Microsoft is already one of them (with it's Windows Mobile phones and XBox at least). Later, when they need to expand their market, they will wipe out the multi-media companies that have become locked in.

      The thing is, and I know this from working in a potential victim company and discussing with the person who was negotiating with MS for media standards, that the extinguish is at least five years away. Almost nobody working in such a company cares about that far in the future.

      Only companies, like Oracle, which decide to fight Microsoft from the beginning as hard as they can, will ever survive long term in such a market.

    Why do you always look at Microsoft will "all" the disdain?

    Experience.

    Fool me once, shame on you. Fool me twice ... umm... you won't get fooled again.

    Snide comments aside, it's simply that it's been too many times the case. Of course MS is in the business to make money. But to that end, vendor lock-in is one of the golden tickets to cash cows. If you can monopolize, you can charge whatever you want and nobody can undercut you. You can dictate price, conditions and format, what your user may or may not do with your tools and so on.

    Yes, MS is in the business to make money. And doing what we "accuse" them to do is the easiest, most profitable and most sustainable way. So I guess we might be correct?

    The SD Association has adopted exFAT for its SDXC memory card specification.

    So a mediocre but patent encumbered technology gets adopted as a standard because it runs out of the box on Windows. As Microsoft itself puts it, "exFAT is relatively simple". Hello, antitrust regulators? Hello, patent office?

      It's still a FAT variant, which means that seeking in a file is an O(n) operation (it's O(log(n)) on most systems) in terms of the size of the file. They've added a free space bitmap, but creating and appending to a file is still O(n) in terms of the size of the disk, just with a smaller constant. Both the FAT and the free space bitmap need to be kept in RAM for reasonable performance. The FAT size depends on the disk size and the configuration, but a typical 32GB memory card will need 32MB for the FAT. This is a lot of memory for a mobile device. Something like the N900 has 32GB of Flash and only 256MB of RAM. You're using an eighth of the RAM just for the FAT. More if you add another memory card, and that's not counting the free space bitmap (also needs to be in RAM, but is quite a bit smaller), ACL or file caches or any other driver overhead.

      Oh, and the FAT itself needs to have individual words updated in a large contiguous section, which is about the slowest operation possible for Flash. They could improve this by using -1 instead of 0 to indicate free sectors: then allocating a sector would not require erasing a flash sector, but deallocating would.

    Almost every computer available? Hardly. From the article: "The technology is available on Windows 7, Vista SP1, Windows Server 2008 and Windows Embedded CE". That's it. The Win 98, 2000, and XP systems you'll find in the wild won't support it. Some of the older systems (ie, XP) can be patched with an update from Microsoft, but are you going to carry a second removable media device with FAT16 or FAT32 around with you and install this patch everywhere you go? And bring XP or later as well for those machines running 98/NT4/2K? I don't believe there's Apple support either, and Linux support is still experimental.

    I haven't seen the spec for exFAT (I'm not paying some fee to see a spec for some microsoft cruft), but I imagine it's another vendor-lockin, poor-performance-substitute abomination like NTFS was, or WinFS will be.

    What exactly is evil? Firstly, they haven't created a standard. If they had then surely they would have published the specifications somewhere. exFAT is a proprietry file format.

    I don't know if they expect everyone to use it, although they may hope that everyone uses it.

    Everything that wants to SDXC will have to use exFAT. It's part of that standard. This is going to be inconvenient for anyone who wants to use their shiny new camera/camcorder on a Mac or linux netbook or someone else's XP machine.

    Since exFAT apparently is referenced in the SD standard, people will be forced to use it, if they buy any consumer electronic device containing an SD slot. They can't choose not to use it. It's a hardware standard.

    So after exFAT, they won't be able to do what they do today, that is, freely exchange their media among their devices at their will. That's evil, and once again, it comes from Microsoft.

    Well, the CD-ROM standard they support is "Joliet". Which is their own extension.... I wonder how long until they are going with patents after others implementing it.

    ISO-9660 doesn't support Unicode. Believe it or not, some languages use characters that aren't part of ASCII.

    ISO-9660 doesn't support lower case letters, spaces and multiple dots in file/directory names.

    There's nothing wrong with naming a directory "Family Photos 25.12.2009." - if Joliet didn't exist, we'd have to burn that to CD as "FAMILYPHOTOS25122009".

    Microsoft is in the business of making money and licensing of its wares is just part of the game. What's wrong with that? Did you want Microsoft to go the Linux way and "donate" the software for "free?"

    Get a life...Have some faith.

    Well, what is wrong in the customers resisting the profit motivated actions of their vendors? Customers have as much right to protect their money as does Microsoft have for making their profits.

    Some actions of the vendors, including Microsoft, enhances the productivity and competitiveness of their customers. Rightfully the vendors, including Microsoft, are entitled to a share of the extra profits generated. But some other actions by the vendor, does not enhance the productivity or competitiveness of their clients, and the customer would be better served by switching to a competitor of the current vendor. Actions by the current vendor that prevents this switch by vendor lock would hamper the clients from employing their money, maximizing their profits etc. And we have as much right to highlight to potential long term danger and make everyone aware of it.

    Why is Microsoft and its apologists are so against people making informed decisions? Vendor lock is real. Companies are hurting from it.

    > Unless Microsoft somehow coerced the association to select exFAT

    Of course they did.

    Microsoft do not support third-party file system drivers. It's certainly possible to write them, but documentation is scarce, there are few tools available, and it's intended for use only in embedded systems. It's not possible to provide the same level of integration as the Microsoft-provided drivers, since none of the disk management tools are extensible by anyone but Microsoft. The IFS drivers themselves are far more complicated than filesystem drivers in any other operating system, since they have to implement functionality that is normally provided by the operating system's VFS layer, and that functionality isn't well documented. Basically, all existing third-party IFS drivers suck.

    The SDXC committee needed the memory cards to be usable on Windows, ideally without installing any drivers, and without having to screw around to get it to work. NTFS is completely unsuitable for flash storage, and is far too complex to implement in an embedded device anyway (not that Microsoft actually license any part of NTFS out to third parties anyway).

    That leaves UDF, which can not be used on anything but optical discs in Windows XP, FAT16, which can't be used for drives larger than 2GB, and FAT32. FAT32 can actually scale well into the terabyte range, but Windows will refuse to format a disk as FAT32 if it's larger than 32GB.

    Microsoft's solution was exFAT. The selection of exFAT instead of FAT32 was forced by limitations on Windows' FAT32 support. These limitations were intentional - the idea was to get people to use NTFS instead of FAT32. The only party to benefit from this situation is Microsoft - they get to sell licenses for their (apparently) patented new filesystem, which they can't do with FAT32 (cameras never used the patented VFAT extensions). In addition, they get to kill off one of their own filesystems, which was being used as a common interchange filesystem between completely different systems, none of which needed to run Windows, or use any Microsoft technology.
