Each Gmail/Google account comes with 15GB of storage for you to use as you please, and you can always up the storage by paying Google. I haven't done that myself as I have multiple Gmail accounts and I just save files on a few of them. Anyway, have you ever ran out of this 15GB of storage yet? I'm close to running out on one account, but I think it's because of the amount of emails I have on there. I'm just too lazy to go in and delete any lol.
