Starting with DOS 3.0, the way to do installable file systems was identical to adding a network drive. (DOS 4.0 had explicit IFSes; nobody used them to my knowledge and it chewed up RAM, and the code was removed in 5.0.)
A “network redirector” basically hooks every possible file I/O operation; DOS simply dispatches to it for any operations on that drive letter.
