>**Note:**  Mount points can be used to support remote mount points on SMB based network shares. This type of share is not supported for BitLocker encryption.
 
For thinly provisioned storage, such as a Dynamic Virtual Hard Disk (VHD), BitLocker runs in Used Disk Space Only encryption mode. You cannot use the **manage-bde –WipeFreeSpace** command to transition the volume to full-volume encryption on these types of volumes. This occurs because Full
Encryption requires an end marker for the volume and dynamically expanding VHDs do not have a static end of volume marker.
