from platform SDK doc
DWORD GetFileSize(
HANDLE hFile, // handle to file
LPDWORD lpFileSizeHigh // high-order word of file size
);
If one expects file to be larger than 4GB, pointer to DWORD variable need to
be passed as second paramter to this function.This varible contains high
word value of file size.
Paul,
But GetFileSize() returns the file size in DWORD-32bit, isn’t it.
that restricts it to 4GB…chaitanya
