Doesn't change drive colors

before defragmentation - post-31867-127796903157_thumb.jpg

and after it - post-31867-127796904233_thumb.jpg

there is one file not defrag, but it's about 10% off all red sections...

Well, with such a small drive/partition, that is possible - but highly unlikely to happen. What is the file that doesn't want to be defragmented ?
