Step-by-step solutions
Review available space
Identify the storage used by the operation.
Check free SSD space and the categories using it.
- Settings
- Storage
Compare with the operation’s space requirement if the console displays one. Review options before selecting content to delete.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Free space through a deliberate selection
Do not confuse a recoverable installation with a unique save or capture.
Review games, apps and media. Before confirming deletion, identify the item and check whether you can reinstall it or have a copy of what you want to keep.
Delete only the selected items, check free space and retry the operation. Do not remove saved data to gain space without protecting it first.
Still not working?
If the same code returns, give PlayStation the free space, operation and displayed requirement. Do not add network tests or system recovery to a capacity problem without other evidence.
