This specification is not "full". There are missing important details, like how is TexFAT implemented. In that specification is just reference to other unpublished documents. So it is classic MS way, they release something incomplete and incompatible with their own NT implementation, like with FAT32 vs fastfat.sys. I would be very very careful about existence of such documentation until somebody implement it and do some testing against MS own implementation. -- Pali Rohár pali.rohar@gmail.com
