A. I wrote the linked script to check a folder and all child folders for all VHDs and then display the current and possible maximum size. It's not the prettiest, but I was in a hurry to get something functional. The next step would be to combine this with a check on the total size of the drive and its free space to see how much you’ve overcommitted the drive with dynamic disks—I'll write that up in a future FAQ.
The script is shown running below.
