I remember defragmentation from ca. Windows 95 times, and it was totally different from this game. None of the files shown here is actually fragmented, only the used space is, and for some reason you can't place a two-block file across a "line break".

edit: I realized that the "lines" might be meant to represent disk cylinders in the pre-LBA era, but even then, a line should "wrap around" to itself instead of the next line.

for the next level each file could have a different color. then multiple blocks of the same color would be one fragmented file. in easy mode the order of the blocks would not matter as long as all of one color follow each other, in hard mode the blocks would have to be in a specific order.

i would also allow blocks be moved freely with the goal to move as little data as possible.
