Quoting OP's:

|> it inspired me to create this small game.

It was inspiration, not a simulation nor it claimed to be realistic. This is the type of artistic license that game designers have always had at their disposal.

I am not complaining about how the game works, I am just saying that there are no instructions, so the only thing I have to work with is the name and the inspiration. And if you know how defragmentation works, this all just makes no sense, why does it automatically select blocks, why can I not move them repeatedly and to any free space? Sure, most people do not know what defragmentation is and how it works, even in developer circles I would not expect people to know if they are not old enough to have worked with computers in the 90s, they might hear about this in one computer science lecture and never think about it again.
