But I do not know anything about '$MFT'.

It is basically a normal file with inode number 0 (this is defined in the ntfs specifications) which contains all metadata concerning all inodes (including the metadata describing the $MFT itself[1]).

Best regards,


[1] Yes, this is a circular reference, but the partition's bootsector contains sufficient information to resolve it unambiguously by pointing you to the disk sectors containing the metadata for $MFT itself). This is also why it has to be inode zero, otherwise the resolution of the circular reference wouldn't work any more.
