Members

The MSFT_DedupFileMetadata class has these types of members:

Methods

The MSFT_DedupFileMetadata class has these methods.

MethodDescription
Measure

Returns a class representing the deduplication metadata for a specified file.

 

Properties

The MSFT_DedupFileMetadata class has these properties.

DedupChunkCount
Data type: uint64
Access type: Read-only

The number of variable-sized chunks that are used in the optimized file.

DedupDistinctChunkCount
Data type: uint64
Access type: Read-only

The number of variable-sized chunks that are used in the optimized file, but are not used by other optimized files.

DedupDistinctSize
Data type: uint64
Access type: Read-only

The size of the unique portion of the file, in bytes, after it has been optimized.

DedupSize
Data type: uint64
Access type: Read-only

The size of the file, in bytes, after it has been optimized.

FilesCount
Data type: uint64
Access type: Read-only

The number of files on the volume.

OptimizedFilesCount
Data type: uint64
Access type: Read-only

The number of optimized files on the volume. This number remains unchanged as users delete files from or add files to the volume—until you run a garbage collection job. This number is most accurate after a garbage collection job runs.

Path
Data type: string array
Access type: Read-only

The path of the file.

Size
Data type: uint64
Access type: Read-only

The size of the file, in bytes, before it was optimized.

SizeOnDisk
Data type: uint64
Access type: Read-only

The amount of space that was allocated to the file before it was optimized, in bytes, based on the cluster size of the partition.

Volume
Data type: string
Access type: Read-only

A drive letter, for example, "D:", or a volume GUID path for the volume.

VolumeId
Data type: string
Access type: Read-only

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.
