Content hosting storage service is upgradable over 50MB as a monthly subscription service. The pay-as-you-go plan option is not applicable. Upgrade subscriptions can be canceled anytime if you want. When you cancel, your storage size limit will be reduced after the paid subscription period. If your then-current consumption has already exceeded the limit, no more files will be allowed to upload. You will have a grace period of 30 days to fix the problem or delete any unwanted files manually. After the grace period, files will be deleted automatically, oldest first, until your consumption falls within your limit again.
