MK Armageddon is twice its size? what?

Posted by jumbo on .

The game was a 2gb download, extracting it made it 4gb. and that's causing my problem of moving it onto my USB drive where it says "file too large for destination file system". I need to put it on this drive so I can put it on my Steam Deck. It should work, because files under 4gb will transfer, and this "2.02gb"game is now 4.06? I can work around this, but should it actually be that big?
