0x80070070
Microsoft Xbox
Severity: ModerateWhat it means
Error 0x80070070 means your Xbox does not have enough storage space to install or update the game.
You need to free up space by deleting games, apps, or clearing cached data.
You can also move games to an external drive.
Affected Models
- Xbox Series X
- Xbox Series S
- Xbox One
- Xbox One S
- Xbox One X
Common Causes
- Internal storage full — not enough space for the game or update
- Game update requires more temporary space than available
- Too many games installed simultaneously
- Xbox Series S has only 364GB usable — fills up quickly with modern games
How to Fix It
-
Go to Settings > System > Storage to check available space.
This shows how much space is used and how much is free.
Modern games can be 50-150GB, so space fills up fast. -
Delete games you are not currently playing.
Go to My Games & Apps > Manage > select a game > Uninstall.
Your save data is kept in the cloud — you can reinstall anytime without losing progress. -
Move games to an external USB hard drive.
Any USB 3.0 drive 128GB or larger can store Xbox games.
Xbox Series X/S games must be on the internal SSD or Expansion Card to play, but Xbox One games can run from external USB. -
Clear local saved data and cache.
Settings > System > Storage > Clear local saved games.
This removes local copies (cloud saves are kept).
Also try a full power cycle: hold the Xbox button for 10 seconds.
