Fields

vnc_first: u64

The lowest virtual cluster number (VCN) covered by this attribute record.

vnc_last: u64

The highest VCN covered by this attribute record.

datarun_offset: u16

The offset to the mapping pairs array from the start of the attribute record, in bytes. For more information, see Remarks.

unit_compression_size: u16

Reserved UCHAR[6]

padding: u32

allocated_length: u64

The allocated size of the file, in bytes. This value is an even multiple of the cluster size. This member is not valid if the LowestVcn member is nonzero.

file_size: u64

valid_data_length: u64

Contains the valid data size in number of bytes. This value is not valid if the first VCN is nonzero.

total_allocated: Option<u64>
