I'm reading about the NTFS attribute types and it come to the $FILE_NAME attribute structure. Here it is:
Offset Size Description
~ ~ Standard Attribute Header
0x00 8 File reference to the parent directory.
0x08 8 C Time - File Creation
0x10 8 A Time - File Altered
0x18 8 M Time - MFT Changed
0x20 8 R Time - File Read
0x28 8 Allocated size of the file
0x30 8 Real size of the file
0x38 4 Flags, e.g. Directory, compressed, hidden
0x3c 4 Used by EAs and Reparse
0x40 1 Filename length in characters (L)
0x41 1 Filename namespace
0x42 2L File name in Unicode (not null terminated)
What is "Filename Namespace" at the offset 0x41? I know a little about namespace i think. How can it be stored in just 1 byte? Can anyone clear this for me? Thank you.
