Calculate Azure VHD actual/billing size

Azure blob storage is billed based to how much data you use. So you can have an 1023 GB disk but if you use only 20 GB you will be billed for 20 GB. But, 🙂 , if you write more data, lets say 50 GB and then you erase them, the free space will not automatically be released.

You can download the executable at:

The command is:

wazvhdsize.exe “storageaccountname” “storageaccountaccesskey==” containername
