Thank you for testing the driver! :-)

I took a look and it seems there is indeed a tiny accounting bug but not 
what you think ;-)

Directory files grow dynamically as new items are added to them but they 
don't shrink when files are deleted. That is, the space remains allocated. 
This is how most file systems work.

You can check this out, for example, by running 

        ntfsinfo -fvi 4071 your_ntfs.img

The directory file is the $INDEX_ALLOCATION attribute and its allocated 
size is 6094848 bytes or 5,9 MB. 

However if you check the allocated sizes in bytes then you can find that 
the two values equal which means that the sum of the allocated sizes (1kB) 
of the two other non-resident attributes isn't counted as it should have 
been.

Thanks for the bug report,

        Szaka
