I am getting a notification that my disk space is full on my xbox one while playing project ...

I'm one xbox one and I have over 200gb left. But I can't save my game while playing project spark, it says my disk space is full. I've deleted everything but that world yet still no progress I had to quit without saving and lost a good bit of work. I don't
understand how my disk space can be full when it's more than half empty. Any help would be great, thanks.

Project Spark turns FREE...

The unexpected Project Spark achievements had me a little freaked out too. I was working on my computer (Win 10 OS) yesterday and kept getting notifications of achievements unlocking, when I knew my Xbox One was off and sitting quietly in the next room
over. Nothing like a little pre-Halloween paranormal Xbox activity!

The new title update will be a good prompt for me to explore Project Spark a little more.

 

Xbox One Memory

Okay, so the other day I bought Watch Dogs for the Xbox One and began to download it when my Xbox told me that my memory was already completely full. I was definitely stunned by this and when I went to check the memory usage sure enough 99.7% of my memory
was taken up. I have 17 games, but only 4 of them are not on a disk. However, when I checked to see how much memory certain games were using up games like Call of Duty or NBA were taking up over 40 GB. What I'm not understanding is how these games can take
up so much space when I have the disk. Also I tried to play these games without the disks in and it said I needed the disks to play. I don't see how deleting my previous games could be my only solution to playing new games.
