Implementing basic file system

Question

As a college project I need to implement a basic file system from within a file. So how do I go about this? What are the things that I would need to know? The requirements include having a daemon process in the background. Also the applications that use this system need to connect to the server using a Unix domain socket

The file system should have the following capabilities:

1. List files stored along with their sizes.
2. Create files
3. Allow changes to files
4. Delete files
