A: The transfer limit is the amount of data included for sent and received files through your account. Just like a cellphone data plan, additional fees will apply based on usage over and above the transfer limit. An account holder can check the status of their account at any time.

For example, if someone sends you a 20MB file, and you download the file once, the total amount of data transferred is 40MB. If you download the file twice, then the total amount of data transferred is 60MB. Deleting a file does not affect the amount of data transferred.
