Fortnite update is too big what to do?

I started installing my update. It was 4GB. Then I canceled it because it didn't work anymore.

But now the update is 18 GB.

What can I do that the update is as big as before

I also asked others, but for all of them the update is only 4 GB.

Bad sectors probably

Delete the update directory / file anyway and reload it and do not choke it this time

Delete Fortnite
and just reinstall
Otherwise you uninstall it, then you have space ^^
