A - fFAT (1 bit): A bit that specifies whether the path is valid on FAT file systems. If fNonFileSys is nonzero, this value MUST be zero.

B - unused1 (1 bit): This bit is undefined and MUST be ignored.

C - unused2 (1 bit): This bit is undefined and MUST be ignored.

D - fNTFS (1 bit): A bit that specifies whether the path is valid on NTFS file systems. If fNonFileSys is nonzero, this MUST be zero.

E - fNonFileSys (1 bit): A bit that specifies whether the path is not a native file system path. If this value is nonzero, the path is not a native file system path, and therefore requires an external file I/O protocol. If this value is zero, the path is native and can be used by the native Windows file I/O API.

F - unused3 (2 bits): This field is undefined and MUST be ignored.

G - unused4 (1 bit): This field is undefined and MUST be ignored.
