AllocationSize (8 bytes): A 64-bit signed integer that contains the file allocation size, in bytes. The value of this field MUST be an integer multiple of the cluster size.

EndOfFile (8 bytes): A 64-bit signed integer that contains the absolute end-of-file position as a byte offset from the start of the file. EndOfFile specifies the offset to the byte immediately following the last valid byte in the file. Because this value is zero-based, it actually refers to the first free byte in the file. That is, it is the offset from the beginning of the file at which new bytes appended to the file will be written. The value of this field MUST be greater than or equal to 0.

NumberOfLinks (4 bytes): A 32-bit unsigned integer that contains the number of non-deleted links to this file.

DeletePending (1 byte): A Boolean (section 2.1.8) value. Set to TRUE to indicate that a file deletion has been requested; set to FALSE otherwise.

Directory (1 byte): A Boolean (section 2.1.8) value. Set to TRUE to indicate that the file is a directory; set to FALSE otherwise.

Reserved (2 bytes): A 16-bit field. This field is reserved. This field can be set to any value, and MUST be ignored.

This operation returns a status code, as specified in [MS-ERREF] section 2.3. The status code returned directly by the function that processes this file information class MUST be STATUS_SUCCESS or one of the following.
