_FILE_DIRECTORY_INFORMATION

incomplete layouts only for what the kernel debuggers decode; other types are named by the kernel's ASSERT text, without layouts

struct _FILE_DIRECTORY_INFORMATION;/* named only */

Named, without a layout, by FIELD_OFFSET in NTOSKRNL.EXE's ASSERT text for this build (a debug build keeps each assertion's source text): FIELD_OFFSET( FILE_DIRECTORY_INFORMATION, NextEntryOffset ) == FIELD_OFFSET( FILE_FULL_DIR_INFORMATION, NextEntryOffset ) It says FILE_DIRECTORY_INFORMATION; recorded builds name the struct _FILE_DIRECTORY_INFORMATION (NT's typedef struct _X {…} X convention). Members it names: AllocationSize, ChangeTime, CreationTime, EndOfFile, FileAttributes, FileIndex, FileNameLength, LastAccessTime, LastWriteTime, NextEntryOffset.
