Unitypackage files wastes space?

Is the .unitypackage a compressed format or it takes more unnecessary space? I bought a sound pack, the .unitypackage is 650MB but when imported, the files are only 350MB. And I can use 7z to compress them to 190MB.

I notice this file wastage in lots of unitypackages too.

It’s compressed; you can uncompress it manually and see what’s inside if you want.

I think the OP means the data inside the package once decompressed is smaller than the package.

It’s not, though; there’s previews and metadata and stuff in there. Looking at a package now, I see the metadata is typically about as large as the asset itself, which seems a bit odd.
