Today, there are many implementations of distributed file systems.
The first file servers were developed by researchers in the 1970s, and the Sun's Network File System were disposable in the early 1980.
Before that, people who wanted to share files used the [[sneakernet]] method. Once the computer networks start to progress, it became obvious that the existing file systems had a lot of limitations and were unsuitable for multi-user environments. At the beginning, many users started to use [[FTP]] to share files.<ref>{{harvnb| |p=1|id= sun}}</ref> It started running on the [[DPD-10]] in the end of 1973. Even with FTP, files needed to be copied from the source computer onto a server and also from the server onto the destination computer. And that force the users to know the physical addresses of all computers concerned by the file sharing.<ref>{{harvnb| Fabio Kon |p=1 |id= Fabio}}</ref>
