AndXCommand (1 byte): The command code for the next SMB command in the packet. This value MUST be set to 0xFF if there are no additional SMB command responses in the server response packet.

AndXReserved (1 byte): A reserved field. The server MUST set this field to 0x00 when this response is sent, and the client MUST ignore this field.

AndXOffset (2 bytes): This field MUST be set to the offset in bytes from the start of the SMB Header (section 2.2.3.1) to the start of the WordCount field in the next SMB command response in this packet. This field is valid only if the AndXCommand field is not set to 0xFF. If AndXCommand is 0xFF, this field MUST be ignored by the client.

OpLockLevel (1 byte): The OpLock level granted to the client process.

Value

Meaning

0x00

No OpLock granted.

0x01

Exclusive OpLock granted.

0x02

Batch OpLock granted.

0x03

Level II OpLock granted.

FID (2 bytes): A FID representing the file or directory that was created or opened.

CreateDisposition (4 bytes): A 32-bit value that represents the action to take if the file already exists or if the file is a new file and does not already exist.

Name and bitmask

Meaning

FILE_SUPERSEDE

0x00000000

The file has been superseded.

FILE_OPEN

0x00000001

The file or directory has been opened.

FILE_CREATE

0x00000002

The file or directory has been created.

FILE_OPEN_IF

0x00000003

The file has been overwritten.

FILE_OVERWRITE

0x00000004

The file already exists.

FILE_OVERWRITE_IF

0x00000005

The file does not exist.

CreateTime (8 bytes): A 64-bit integer value representing the time that the file was created. The time value is a signed 64-bit integer representing either an absolute time or a time interval. Times are specified in units of 100ns. A positive value expresses an absolute time, where the base time (the 64- bit integer with value 0x0000000000000000) is the beginning of the year 1601 AD in the Gregorian calendar. A negative value expresses a time interval relative to some base time, usually the current time.

LastAccessTime (8 bytes): The time that the file was last accessed encoded in the same format as CreateTime.

LastWriteTime (8 bytes): The time that the file was last written, encoded in the same format as CreateTime.

LastChangeTime (8 bytes): The time that the file was last changed, encoded in the same format as CreateTime.

ExtFileAttributes (4 bytes): This field contains the extended file attributes that the server assigned to the file or directory as a result of the command, encoded as an SMB_EXT_FILE_ATTR (section 2.2.1.2.3) data type.

AllocationSize (8 bytes): The number of bytes allocated to the file by the server.

EndOfFile (8 bytes): The end of file offset value.

ResourceType (2 bytes): The file type. This field MUST be interpreted as follows.

Name and value

Meaning

FileTypeDisk

0x0000

File or directory

FileTypeByteModePipe

0x0001

Byte mode named pipe

FileTypeMessageModePipe

0x0002

Message mode named pipe

FileTypePrinter

0x0003

Printer device

FileTypeCommDevice

0x0004

Character mode device. When an extended protocol has been negotiated, this value allows a device to be opened for driver-level I/O. This provides direct access to devices such as modems, scanners, and so forth.

NMPipeStatus (2 bytes): A 16-bit field that shows the status of the named pipe if the resource type opened is a named pipe. This field is formatted as an SMB_NMPIPE_STATUS (section 2.2.1.3).

Directory (1 byte): If the returned FID represents a directory, the server MUST set this value to a nonzero value (0x01 is commonly used). If the FID is not a directory, the server MUST set this value to 0x00 (FALSE).

SMB_Data (2 bytes):
