DWORD GetFileSize( HANDLE hFile, LPDWORD lpFileSizeHigh);
Parameters
hFile
[in] Open handle of the file whose size is being returned. The handle must have been created with either GENERIC_READ or GENERIC_WRITE access to the file.
lpFileSizeHigh
[out] Pointer to the variable where the high-order word of the file size is returned. This parameter can be NULL if the application does not require the high-order word.

Вот пример:

Цитата

//
// Case One: calling the function with
// lpFileSizeHigh == NULL

// Try to obtain hFile's size
dwSize = GetFileSize (hFile, NULL) ;

// If we failed ...
if (dwSize == 0xFFFFFFFF) {

// Obtain the error code.
dwError = GetLastError() ;

// Deal with that failure.
.
.
.

} // End of error handler


//
// Case Two: calling the function with
// lpFileSizeHigh != NULL

// Try to obtain hFile's huge size.
dwSizeLow = GetFileSize (hFile, & dwSizeHigh) ;

// If we failed ...
if (dwSizeLow == 0xFFFFFFFF
&&
(dwError = GetLastError()) != NO_ERROR ){

// Deal with that failure.
.
.
.

} // End of error handler.
