Of course, a file system can be implemented and work in real mode, but it will have some limitations caused by real mode itself.

For the most basic setup, you need to implement:
1) functions to read/write raw sectors (using BIOS int 0x13)
2) file system functions that use those in part 1

First learn what a file system is
http://en.wikipedia.org/wiki/File_system
http://wiki.osdev.org/File_Systems

and take a look at MiniDOS

You can't expect too much. People here have limited time and explaining in detail the things you ask is very time consuming. Please try to receive links also as part of the deal. Often the links can give very detailed and relevant answers to your questions and allows the responders to give you the info you want without spending hours of their own time to say exactly the same things without links.
