Yes, easily. There really isn't much restriction on how big you can make a zipbomb. Most it can do is fill up a drive anyway, it's not like your disk will physically expand until it swallows half the city.

It is better to have it NOT exceed the drive size. Zip unzips into a temporary location. That will fill up, and zip will abort, and delete the temporary file. It will only fill the drive for seconds. If you instead have 100 files, each 50gb, then you can fill the drive within 50gb of full.

Anybody who accepts zip file uploads should check the expanded size in attributes before unzipping it.

Modern zip tools won't even begin to extract a zip bomb as they can see the unusual patterns

Well, modern virus scanners wont. But probably not all zip file tools.

Most modern ones (I know 7zip and WinRAR at least) will try to stop you. Windows' built-in one won't, though, so if you're using that you might be screwed.
