PlayStation 5 launch disc model storage is full or games will not install

The checks in more detail

For large games such as the big shooters, you can delete the parts you do not use: some games let you uninstall the multiplayer or the campaign separately, from the game's options menu, by selecting Manage Game Content. Clear the Media Gallery of game captures and videos, which can be a few gigabytes. Check the Downloads and Updates list for pending downloads that use space. If the console says there is not enough space for an update, delete something before starting the update. Add more storage. The PS5 has an M.2 expansion slot under the side cover, and Sony lists the drive specifications, including a heatsink, for a compatible NVMe SSD;

open the cover as Sony's instructions show and fit the drive. A USB extended storage drive can hold PS4 games and PS5 games for storage, but PS5 games can only be played from the internal drive or an M.2 drive. After fitting a drive, format it in Settings, Storage. Move games between locations in Storage settings. Back up your saves to the cloud through PlayStation Plus before any storage change. Contact PlayStation support if the storage numbers look wrong. The PS5 shows a bar of how the storage is divided, and the Games and Apps portion is the one to trim.

Games can be sorted by size, and you can select several at once and delete them. A quick check of Settings, Saved Data and Game/App Settings, Saved Data, shows how much is held locally; saves for a deleted game stay, and with PlayStation Plus you can keep them in the cloud. Updates to a large game can need as much free space again as the update itself, so leave at least ten gigabytes spare. The console can also move PS4 games to an extended USB drive from the Storage menu.
