Open Source ExFAT File System Reaches 1.0 Status
Titus Andronicus writes "fuse-exfat, a GPLv3 implementation of the exFAT file system for Linux, FreeBSD, and OS X, has reached 1.0 status, according to an announcement from Andrew Nayenko, the primary developer. exFAT is a file system designed for sneaker-netting terabyte-scale files and groups of files on flash drives and memory cards between and among Windows, OS X, and consumer electronics devices. It was introduced by Microsoft in late 2006. Will fuse-exfat cut into Microsoft's juicy exFAT licensing revenue? Will Microsoft litigate fuse-exfat's developers and users into patent oblivion? Will there be a DKMS dynamic kernel module version of the software, similar to the ZFS on Linux project? All that remains to be seen. ReadWrite, The H, and Phoronix cover the story."
As far as I know it's part of OS X since Snow Leopard. But I could totally use the Linux support.
You do know what a "Sneaker Net" is dont you ? I guess not. It is using media such as SD Card or USB stick or hard drive to move files from one location to another by walking ie on your feet that are wearing sneakers, also very similar to using a "V8" net as in "Never underestimate the bandwidth of a V8 station wagon loaded with tapes / drives hurtling across the country"
Standardise all you want. You should know what'll happen. Windows will not support it out the box, and if Windows doesn't support it, that filesystem is effectively dead. Who is going to want a USB stick formatted so it won't work on the operating system running on upwards of ninety percent of desktops and laptops?
Microsoft has already won by having ExtFAT part of the SDXC spec, so every big SD card comes with it. The only thing the Open Source world can do is damage control by implementing it and thus staying useful.
Based on their previous actions, they will allow the use of this project in distros but will sue any commercial implementation that uses it. So they haven't sued Ubuntu or Mint, but have sued TomTom.
Am I allowed to use this implementation?
Depends on what you want to use for: as a form of expression, you should be able to. Use the binary form to read/write, all depends on the MS patents and whether or not MS grants you a license.
Will Microsoft litigate fuse-exfat's developers and users into patent oblivion?
Regarding developers: the software is posted as source code with instructions on how to install them from source. Being source code, is a form of expression, protected by copyright. As such, can a commercial entity try to block the dissemination of the "speech" that the source code constitutes?
Mind you, any existing patents should not play any role into it: after all a patent is a public disclosure of methods/constructs that constitute the invention (the text of the patent is not copyrighted), so the source code should not be anything but an alternative form of expression of the same.
Regarding users: yes, using the compiled binaries would violate the temporary monopoly granted by any existing patents. However, I can't imagine any corporations starting to track which hobbyist home users:
1. downloaded the source code - should not be, per se, illegal - the copyleft license allows you to do it and the patent should not trump the copyright.
2. for each of them, ask for a discovery to see if that source code has been compiled - again, compilation should not be illegal, I'm obtaining a derivative form of expression and the GPL copyright license allows me to do it
3. use the binary - this is the only step that would violate the patent
Questions raise, answers kill. Raise questions to stay alive.
Not that we're anywhere close to terabyte flash drives.
You sure about that?

They're not cheap yet, but they're here.
