Why are microsoft store games taking up so much space?

Installing and downloading Forza 7. As I started the download my SSD space went down 100GB. and now during the download my SSD space is going down by 1gb every 2 minutes ?

Will the OS delete the temporary files after downloading ?

After some searching for the missing data. There's a 100GB " Cache " file stored on the SSD. I'm assuming this will disappear afterwards.

Think I found the culprit. Delivery Optimization was taking up loads of space, disabled it now the game seems to be taking up the correct amount of space
