I bought an external drive to download some games. I was able to download the apps directly to eh external drive, but when you open up games there's a bunch more that the game has to download in-game. And while that was downloading it ballooned up my system data. I should have had plenty of room for the 3 games I wanted to download, but once I got to in game downloads, it ate up my system data immediately and I was only able to install one game. Is there any way to fix this?
