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.
