As i know there are 4 ways to extend a file:
2. NtCreateSection with a size larger than the current file size
3. NtMapViewOfSection(MEM_RESERVE) followed by NtAllocateVirtualMemory(MEM_COMMIT)
4. NtWriteFile with offset larger than file size
Does NTFS fill extended part with zero for all 4 cases? Is there any other way to extend a file?
