NTFS files may have multiple file name attributes (corresponding to hard links), that have the same name (are unnamed) and type ($FILE_NAME).
Are there any other cases where attributes of the same type and name appear multiple times in the same file record?
Looks like only
$FILE_NAMEattribute can present in a file record multiple times with the same type and name. This is implicitly indicated by looking at$AttrDeffile content, where only$FILE_NAMEhas bit 2 (Indexed) set. The rest of the attribute types don’t have this bit set.
