The concept of exclusive access is not portable across platforms and it 
is not supported in Qt. But, I have to ask, why do you need it?

Would writing to a temporary file (e.g, using QTemporaryFile) in the 
same directory as the destination and renaming once transfer is finished 
be enough?

Cheers,
