Would need to review a patent application, if there is one, to really get down to what it's all about.
Anyway, it's all understandable ...it's using bit mapping, or it's not.... as a sub issue of FAT.
or exFAT is a bogus identification....and its not utilizing the issues of either.
I'd say what is on WiKi is close to what it is.
I'm not worrying about exFAT or FTL.....lol
