Parent article: Punching holes in files

If I want to punch a 5GB hole in the middle of a file, I don't want to have to do 5GB of writes to make it happen. And yes, I actually have a use for punching really big holes.

Wouldn't you need to do it anyway when you allocate that space again?

I wouldn't be punching a hole if I intended to fill it any time soon.

In any case, supposing that I did want to punch a big hole, then fill it, I wouldn't want to have to write the whole region twice.
