Re: Just thinking out loud
i am fully aware of how to use a search engine.
In my comment i say OPEN source.
exFAT (Extended File Allocation Table) is a Microsoft file system optimized for flash drives. It is proprietary and patented. so is NOT cross Platform supported or implemented.
It Cant become an official part of Linux due to the patent encumbered status of the exFAT file system.
A real world example of non compatibility is Jolla in their new Sailfish powered Tablet dont support large SD cards due to licencing issues with exFAT. :-(
