My honest opinion of that might cause offense in some quarters !

I'm really lost for what they are looking for. You'll have made all 
empty blocks contain nulls, and when the files are deleted then all 
these blocks will be in the free space list. If that's not enough, 
then I have to wonder what they really want - the moon on a stick, 
some magic pixie dust ?
