FileHandle (8 bytes): A HANDLE ([MS-DTYP] section 2.2.16) data type that is an identifier of the open to the source file.
SourceFileOffset (8 bytes): A 64-bit signed integer that contains the file offset, in bytes, of the start of a range of bytes in a source file from which the data is to be copied. The value of this field MUST be greater than or equal to 0x0000000000000000 and MUST be aligned to a logical cluster boundary.
TargetFileOffset (8 bytes): A 64-bit signed integer that contains the file offset, in bytes, of the start of a range of bytes in a target file to which the data is to be copied. The value of this field MUST be greater than or equal to 0x0000000000000000 and MUST be aligned to a logical cluster boundary.
ByteCount (8 bytes): A 64-bit signed integer that contains the number of bytes to copy from source to target. The value of this field MUST be greater than or equal to 0x0000000000000000 and MUST be aligned to a logical cluster boundary.
