>>> I think we should go for 64 bit numbers already. RES-STORAGE is now limited to 4 terabytes, which is rather high value for a single user's limit for now, but I could imagine it being a possibility in some more years. Maybe even already in email systems that use only a few users. Also there's already an example:
>>>

>>>        S: * QUOTA "!partition/sda4" (STORAGE 104 10923847)
