Access type: Read-only

The unique ID for the data deduplication chunk store.

StreamMapAverageChunkCount
Data type: uint32
Access type: Read-only

This property is reserved for future use.

StreamMapChunkCount
Data type: uint64
Access type: Read-only

The number of stream map chunks on the volume.

StreamMapContainerCount
Data type: uint32
Access type: Read-only

The number of containers in the stream map store.

StreamMapMaxChunkCount
Data type: uint32

Volume
Data type: String
Access type: Read-only

A drive letter (for example, D:) or volume GUID path for the volume.

VolumeId
Data type: String
Access type: Read-only
Qualifiers: key

A volume GUID path for the volume. A volume GUID path is a string of the form "\\?\Volume{GUID}\" where GUID is a GUID that identifies the volume.
