I've had my ps5 since it launched in 2020, and I've recently noticed that I never have enough internal storage. I went into the storage settings, and the "other" tab is taking up 365.8gb! I googled it, and it is only meant to have around 50 to 90gb, I think! Is there a way to decrease it, or do I need to factory reset it? Thanks for any help.
