SMB (samba) is also from the DOS era. Most people only know of it from Windows, though.
There were various other ways to make network "drives" as the DOS drive interface was very simplistic and easy to grab onto.
It was rare to find this stuff until Win95 make network connections "free" (before then, you had to buy the networking hardware and often the software, separately!).
Back in the day, you could author a web page directly in GruntPage, and publish it straight to your web server provided said server had the FPSE (FrontPage Server Extensions), a proprietary Microsoft add-on, installed. WebDAV was like the open-standards response to that. Eventually in later versions of FrontPage the FPSE was deprecated and support for WebDAV was provided.
