Thanks for your response. However, the client side interface details (RFile, RFs) is not what I was looking for.
I am interested in knowing details of the working of the file server (the efile executable itself). How it communicates with the kernel, how it handles client session requests, how it does file lookup, whether it uses server cache or not.
I would also like to know if it has the capability of doing file accesses over the remote network using some communication infrastructure.
