Those who edit wikis will appreciate that wiki text is simply a normal text document edited using a form of wiki syntax. Whether the final storage is a database or a flat file the part that a user edits is a simple text file.

For importing please see Help:Import this is disabled on most wikis so not directly usable currently.
