title: How to get or calculate size of Azure File/Share or Service
body: <p>I am currently building a multi tenant Web App to be hosted in Azure which will use Azure File Services to store each clients data - a distinct File Share will be used for each client to provide isolation.  </p>
  
  <p>My question is - how can I discover the size of all files within a particular file share?  (For billing purposes).</p>
  
  <p>I have PowerShell scripts etc to calculate the size of Blob storage, but nothing for File Storage.  Does anyone know if this is possible and how it can be done, preferably from my C# application?</p>
