My Xbox Series X is missing 25GB of storage

It depends how you're calculating the space used by your games. If you sort by size, that will show the size of your games on their respective tiles, but only the base game sizes; not any DLC.

Also, the console acts a bit weird after a reset as it doesn't take into account the size of any DLC a game has until after you've launched it at least once, then it will register the DLC for that game and your available space will decrease.

So, yeah, it's likely nothing is wrong. If you want to be sure, go into "Manage game" for each of the 7 games and look at the total install size, including DLC, and add that up.

Sometimes it can be included with a game purchase, depending on the version you buy.

But yeah, if you go into "Manage game" for each of your 7 games, you can see the full install size, including any DLC. Given that you only have 7 games installed, it would only take a couple of minutes to check it out.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello LordXeno, you have done the correct procedure in the console, sometimes the system may not delete the temporary system files.

So try a cache wipe and system reset.

Is DLC an add-on? Or does it come downloaded with the game

I haven’t installed any DLCs

Thanks for the reply

Hi,

Both Series X/S games and Xbox One games that been optimised (I'm British) for Series X/S must be installed on either the internal storage or the expansion card. They can not be run from a USB connected storage device. My optimised Series X/S Xbox One games
were moved to my Expansion card during their update.
