 Azure Files provides two distinct billing models: provisioned and pay-as-you-go. The provisioned model is only available for premium file shares, which are file shares deployed in the **FileStorage** storage account kind. The pay-as-you-go model is only available for standard file shares, which are file shares deployed in the **general purpose version 2 (GPv2)** storage account kind. This article explains how both models work to help you understand your monthly Azure Files bill.
