That is the offset into the file. Thus, the read operation begins with the
byte offset. Since files can be up to 2^64 bytes in size, it requires a
quad word (8 bytes) to represent this offset.
This is (or should be) a rather basic driver question. Prior to building a
file system (or filter driver) I would strongly suggest that you need to be
comfortable with device drivers, the I/O subsystem, etc and how they work in
Windows. There are a number of very good books on the topic. Learning to
write drivers, one e-mail at a time to the NTFSD mailing list, is likely to
be a very difficult process for everyone involved.

Hi~~
There is something that I don’t know.
