Properties

The MSFT_DfsrIdRecordInfo class has these properties.

Attributes

Data type: uint32
Access type: Read-only
Qualifiers: DisplayName ("Attributes")

The file or folder attributes. For a list of values, see the GetFileAttributes function.

Clock

Data type: uint64
Access type: Read-only
Qualifiers: DisplayName ("Clock")

The logical clock value assigned to the file or folder.

CreateTime

Data type: datetime
Access type: Read-only
Qualifiers: DisplayName ("Create Time")

The creation time stamp of the file or folder. This is the time at which the resource first appears in the replication group.

Fence

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Fence")

The fence value associated with the file. This property can be one of the following values.

Unfence (0)

This file or folder will lose all conflicts.

Initial Sync (1)

Initial fence value for non-primary member.

Initial Primary (2)

Initial fence value for primary member.

Default (3)

Default fencing value.

Fence (4)

Fence with current time stamp.

Fid

Data type: uint64
Access type: Read-only
Qualifiers: DisplayName ("File ID")

The file reference number. On NTFS, each file is assigned an identifier which is unique on the volume; it can be used to open a handle to the file.

FileHash

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("File Hash")

A hash value for the file content.

FileName

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Relative Name")

The name of the file or folder.

Flags

Data type: uint8
Access type: Read-only
Qualifiers: DisplayName ("Flags")

A combination of flags for present, authoritative, and file type flags.

PRESENT_FLAG (0x1)

The resource is not a tombstone; it is available on the computer.

NAME_CONFLICT_FLAG (0x2)

The tombstone was generated because of a name conflict.

This flag is meaningful only for tombstones.

UID_VISIBLE_FLAG (0x4)

The ID record has already been sent out to other partners; therefore, other partners are aware of this resource.

JOURNAL_WRAP_FLAG (0x10)

The volume has had a journal wrap and the resource has not been checked to determine if there is any change by the journal wrap recovery process.

PENDING_TOMBSTONE_FLAG (0x20)

The ID record is in the process of being tombstoned (or deleted.)

FullPathName

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Full Path Name")

The complete path to the file or folder.

GVsn

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Global Version")

The global version of the resource (file or folder). The format of this string is "{DatabaseGUID}-VersionNumber", where "DatabaseGUID" is the GUID of the DFSR database and "VersionNumber" is an integer value assigned to each resource that increases when the resource is modified. Because the database GUID uniquely identifies the last computer that the resource was modified on, the GVsn property uniquely identifies a particular version of the resource.

Index

Data type: uint32
Access type: Read-only
Qualifiers: DisplayName ("Record Index")

The run-time index of the record. This value is used to partition the result of a large query.

ParentUid

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Parent GUID")

The unique identifier of the parent folder.

ReplicatedFolderGuid

Data type: string
Access type: Read-only
Qualifiers: MaxLen (36), MinLen (36), DisplayName ("Replicated Folder GUID")

The unique identifier of the replicated folder.

Uid

Data type: string
Access type: Read-only
Qualifiers: key, DisplayName ("File or Folder GUID-Version Pair")

The unique identifier of the resource (file or folder). The format of this string is "{DatabaseGUID}-VersionNumber", where "DatabaseGUID" is the GUID of the DFSR database and "VersionNumber" is an integer value assigned to each resource when it is created. Because the database GUID uniquely identifies the computer that the resource was created on, the Uid property uniquely identifies the resource.

UpdateTime

Data type: datetime
Access type: Read-only
Qualifiers: DisplayName ("Update Time")

The last time DFSR updated the record in response to a change in the resource.

Usn

Data type: sint64
Access type: Read-only
Qualifiers: DisplayName ("USN")

The USN (Update Sequence Number) at the time the resource is updated.

Volume

Data type: string
Access type: Read-only
Qualifiers: DisplayName ("Volume")

The volume where the file or folder is located. The volume format is either "\\.\C:" or "\\?\volume{GUID}".
