Why does it take longer to delete big files if all we do is unlinking them ?

Hi guys,

It might appear as a stupid question but I haven't found much googling this, just one guy telling it takes lot of time deleting "multiple blocks linked together". 

Intuitively, I would have thought that deleting time would be linear with the number of files but I guess what I picture as the address location is way more complex in reality.

Can someone please enlighten me ?

The time taken to delete a file is proportional to its size, because a larger file means more chunks to delete. You need to go through and delete all chunks, not just the first chunk.

(Obviously simplified, but that's basically it.)
