Hello,
I have the folowing code:
The file is 4G
status = ZwQueryInformationFile( hoi, &iostatus, &fileinfo,
sizeof(FILE_STANDARD_INFORMATION),
FileStandardInformation);
pDevext->containerinfo.size.QuadPart = fileinfo.EndOfFile.QuadPart;
Why pDevext->containerinfo.size is negative?? because this is happening 
Thanks
