Now, the description of file-server is
A file server is a computer attached to a network that has the primary purpose of providing a location for shared disk access[...]
It seems to have the same problem. Furthermore, if you look at the questions tagged with it, it looks pretty redundant with either sshfs, nfs, samba, or whichever the real daemon used for sharing files is. Ah, and there is also a file-sharing tag.
Do we need both file-server and file-sharing? file-server is useless if one of samba, nfs, etc. is also used and file-server and file-sharing seem pretty redundant. There are only two questions tagged file-sharing.
